Hi,

I think this code should work, but the compiler does not agree.
Am I missing something?

void main()
{
    alias funType = void function(int x);
funType fun = (x) => { assert(x); }; // cannot return non-void from void function
    fun(0);
}

From the language reference I understand that assert shoud return void, so I can't see how this code is wrong.

Wrong syntax!
You mean (x) { assert(x); }

or

(x) => assert(x)
