trying to do this C code, in D, but getting error:

any help much appreciated:

while ((*dst++ = *src++)) {}

You can't use = in a while loop's condition like that in D,
regardless of what you do with parens. You'll need to refactor
the code so that the assignment is done in the loop's body.
This is of course only partly true.
while ((*dst++ = *src++) != 0) {}
works just great, and also better shows what's actually being
tested for in the loop.
