Functions

isCovariant bool isCovariant(bool returnByRef, const Parameter p): Compute covariance of parameters this and p as determined by the storage classes of both.
isLazyArray Type isLazyArray(): Determine if parameter is a lazy array of delegates. If so, return the return type of those delegates. If not, return NULL.

Static functions

_foreach int _foreach(Parameters* parameters, scope ForeachDg dg, size_t* pn = null): Expands tuples in args in depth first order. Calls dg(void *ctx, size_t argidx, Parameter *arg) for each Parameter. If dg returns !=0, stops and returns that value else returns 0. Use this function to avoid the O(N + N^2/2) complexity of calculating dim and calling N times getNth.
dim size_t dim(Parameters* parameters): Determine number of arguments, folding in tuples.
getNth Parameter getNth(Parameters* parameters, size_t nth, size_t* pn = null): Get nth Parameter, folding in tuples.
