I have a question regarding template value parameters.
As this works:
template B(T, T[] foo) {}
I expected
template A(U) {}
template B(T, A!T foo) {}
to work, too. Currently, it failes with "undefined identifier
`T`".
I'm not sure as why T is undefined in this case, as the first
example works properly.
In the same vein:
alias A(U) = int;
template B(T, A!T u) {}
This failes to compile with "undefined identifier `T`", too.
Why is this happening?
I'm using DMD v2.076.0.
template B(T, alias A!T foo) {}
