The expression to resolve as type or symbol.
After typeSemantic the symbol when exp doesn't represent a type.
Covariant means that 'this' can substitute for 't', i.e. a pure function is a match for an impure type.
For pretty-printing a type.
Deinitializes the global state of the compiler.
This version does a merge even if the deco is already computed. Necessary for types that have a deco, but are not merged.
Store this type's modifier name into buf.
Return this type's modifier name.
When T is mutable, Given: T a, b; Can we bitwise assign: a = b; ?
Returns true if T can be converted to boolean value.
Check type to see if it is based on a deprecated symbol.
Return a copy of this type with all attributes null-initialized. Useful for creating a type with different modifiers.
Convert to 'const'.
Convert to 'immutable'.
Make type mutable.
Make type unshared. 0 => 0 const => const immutable => immutable shared => 0 shared const => const wild => wild wild const => wild const shared wild => wild shared wild const => wild const
Convert to 'wild'.
For our new type 'this', which is type-constructed from t, fill in the cto, ito, sto, scto, wto shortcuts.
Look for bugs in constructing types.
Apply STCxxxx bits to existing type. Use *before* semantic analysis is run.
Apply MODxxxx bits to existing type.
Add MODxxxx bits to existing type. We're adding, not replacing, so adding const to a shared type => "shared const"
Add storage class modifiers to type.
If this is a shell around another type, get that other type.
Determine if 'this' can be implicitly converted to type 'to'.
Determine if converting 'this' to 'to' is an identity operation, a conversion to const operation, or the types aren't the same.
Compute MOD bits matching this argument type to wild parameter type.
Return type with the top level of it being mutable.
Return alignment to use for this type.
Use when we prefer the default initializer to be a literal, rather than a global immutable variable.
Return !=0 if the type or any of its subtypes is wild.
Return !=0 if type has pointers that need to be scanned by the GC during a collection cycle.
Detect if type has pointer fields that are initialized to void. Local stack variables with such void fields can remain uninitialized, leading to pointer bugs.
If this is a type of something, return that something.
If this is a type of static array, return its base element type.
Compute number of elements for a (possibly multidimensional) static array, or 1 for other types.
Return the mask that an integral type will fit into.
true if when type goes out of scope, it needs a destructor applied. Only applies to value types, not ref types.
true if when type is copied, it needs a copy constructor or postblit applied. Only applies to value types, not ref types.

Check if the inner most base type is complex or imaginary. Should only give alerts when set to emit transitional messages.
This is a shell containing a TraitsExp that can be either resolved to a type or to a symbol.
The point is to allow AliasDeclarationY to use __traits(), see issue 7804.
