Where is all this whining about imports when it comes to other
simple library functions, like `max` or `abs`? It seems to me
like "having to import" is something that people love to complain
about in DIP threads, but have no trouble with when it comes to
actually writing code.
In any case, the primary goal here (and with the analogous
proposal for reinterpreting casts) is to help D programmers write
correct, readable, and maintainable code, not to minimize the
number of lines they have to type.
