Well, you don't need a comment -- why not allow the condition to come
first?
repeat while ( condition(); )
{ something(); },
{ something_else(); }
You need the comma there because the final semicolon is optional, and
we don't want Perl to think it's an ordinary loop followed by an
independent block. Probably better is to name the introductory block,
and then programmers as well as compilers know that something unusual
is going on:
repeat while (condition)
preamble { something }
{ something_else }
