           Summary: Function call in string mixin inside mixin template
                    without return value mistaken as declaration

Example code:

mixin template CallFkt() {
    mixin("testFkt();");
}

void testFkt() {
    import std.stdio : writeln;
    writeln("Called");
}

void main() {
    mixin CallFkt;
}

Output:

/d534/f170.d(2): Error: function declaration without return type. (Note that
constructors are always named 'this')
/d534/f170.d(2): Error: no identifier for declarator testFkt()
/d534/f170.d(11): Error: mixin f170.main.CallFkt!() error instantiating

Expected output:

Called

Description:

This code works when testFkt returns a value (int for example) and the call is
assigned to a variable (mixin("int i = testFkt();"); for example).
