I disagree. The macro definitions does not need to (and probably should
not) be in the same place as the input file, but they do have to be
defined somewhere.  Yes you can just construct your own string[string]
and hand that over to the macro expander, but it would be nice to also
have a uniform syntax for defining macros in an external source, which
can be parsed by a standard library function.

It would be kinda disappointing to have a marvellous system for macro
expansion, yet no standard way to define said macros, but everyone cooks
their own syntax and parser for it.
