I use them, sometimes, when rewriting in scheme an algorithm
written in imperative style in a foreign language.  For example,
when taking an algorithm from a book.

Sometimes it's worth the time to translate the code in good style,
and sometimes the time is missing.  Luckily, with scheme we have
the choice.

Nevertheless, I'd prefer not to have these macros in the standard.
And I'd strongly prefer not to have them in WG1 scheme.

me too.
