           Summary: Broken return type inference for delegate returns

          Priority: P2
         Component: DMD

This worked in DMD 2.057, but doesn't compile in 2.058:

void main()
{
    int a;
    char[] delegate() b = { a = 0; return null;};
}

Error is:

test.d(4): Error: cannot implicitly convert expression (__lambda1) of type
typeof(null) delegate() nothrow @safe to char[] delegate()

A few more examples that don't work in 2.058 but work in 2.057:

int delegate() a = {return 1U;};
uint delegate() b = {return 1;};
float delegate() c = {return 1.0;};
double delegate() d = {return 1.0f;};

Note that both compilers allow implicit conversions between those basic type pairs.
