Description Tomasz Stachowiak 2007年09月05日 14:50:48 UTC

template Foo(alias a) {}
struct Bar {}
const Bar bar = {};
alias Foo!(bar) baz;
// ----
constaliasbug.d(6): template instance Foo!(Bar()) does not match any template declaration
Works in dmd 1.020, works when the initializer is removed from "bar"'s declaration: 'const Bar bar;' (invalid in gdc, iirc), and works when 'bar' is not const.
This bug breaks Bind, btw.
