import std.typecons: Typedef;
alias Matrix = double[260][260];
alias Foo = Typedef!Matrix;
void main() {}



dmd 2.064alpha gives:

test.d(3): Error: template instance std.typecons.Typedef!(double[360u][260u])
recursive expansion


My main use case for Typedef is with arrays, to tell them apart, to avoid bugs.


This used to work correctly:

alias Matrix = double[260][260];
typedef Matrix Foo;
void main() {
    Foo m;
}
