EMPTY_MACRO_SLOT is a value used for implementing optional arguments for macros in an efficient
|
||||
way. It relies on the fact that distinct types are not implicitly convertable.
|
||||
|
||||
You can use `@is_empty_macro_slot()` and `@is_valid_macro_slot()` to figure out whether
|
||||
the argument has been used or not.
|
||||
|
||||
An example:
|
||||
|
||||
```c3
|
||||
macro foo(a, #b = EMPTY_MACRO_SLOT)
|
||||
{
|
||||
$if @is_valid_macro_slot(#b):
|
||||
return invoke_foo2(a, #b);
|
||||
$else
|
||||
return invoke_foo1(a);
|
||||
$endif
|
||||
}
