As Jonathan explained, you don't have to worry about it if foo()
itself doesn't assign the pointer to anything internally. That

Well, I never bother with "idiomatically", so I can't speak to
that, but a simple solution that would work is to realize that
what you're basically asking for here is a bitmap.

I've been given a challenge to write texts using asterisks to
form the letters. D happen to have an unlimited amount of idioms
yet i'm out out ideas as to the simplest approach. Task is to
basically take a piece of text and write them as asterisks to the

Dchar and byte work as expected.

Important Note: When passing a char* to a C function, and the C
function keeps it around for any reason, make sure that you keep
a reference to it in your D code. Otherwise, it may become

Exactly. If you intend const, just write const. If you intend
const scope, write const scope.
