One expects this code to be valid:
void foo(const(char)* mod = __MODULE__)() {
}
void main() {
foo();
}
However you get the error:
onlineapp.d(9): Error: cannot implicitly convert expression `"onlineapp.d"` of type `string` to `const(char)*`
onlineapp.d(9): Error: template instance `foo!((__error))` incompatible arguments for template instantiation
onlineapp.d(9): Error: none of the overloads of template `onlineapp.foo` are callable using argument types `!()()`
onlineapp.d(3): Candidate is: `foo(const(char)* mod = __FILE__)
While if you do the same with __FUNCTION__ the code compiles:
void foo(const(char)* fun = __FUNCTION__)() {
}
void main() {
foo();
}
