Description Pelle Månsson 2009-10-21 05:19:54 UTC 
Anonymous delegates cannot use automatic type deduction. For example:

int f(int delegate(int) g) {
    return g(13);
}
void main() {
    f((auto x) { return x+13; });
}

This fails to compile. Omitting the 'auto' also fails to compile.

This works now, due to the recent improvements in delegate literal inference and conversions. (dmd 2.058)
