Currently this code is not supported:

void main() {
foo(1, (int a) => a * a); // OK
foo(1, a => a * a); // Error
}
With the latest alpha compiler it gives:
test.d(4): Error: template test.foo does not match any function
template declaration. Candidates are:
test.d(1): test.foo(T)(T x, T function(T) f)
test.d(4): Error: template test.foo(T)(T x, T function(T) f)
cannot deduce template function from argument types
!()(int,void)
Do you think it's a good idea to allow it?
Bye,

The second is template lambda and templates have void type. What
you suggest here?
