Because inevitably someone will write:
#define FOO a + FOO
and expect it to work (the correct expansion would be "a + FOO", not a
stack overflow). The C preprocessor works this way, as do makefile
macros, as Ddoc does.
Makes sense, but why is it an issue if expansion is explicit?
enum FOO = q{a + FOO};
mixin(FOO);
Because the expanded text is then rescanned for further macro replacement.
Yes, but in q{a + FOO} there is none.
