Did someone say golf?
sub chain{(*f,*_)=@_;@_=&$_ for@f;@_}
Of course you probably want strict compliant and it is bad style to modify your arguments in place. In which case it is probably better to make that:
sub chain{my($f,$a)=@_;$a=[&$_(@$a)]for@$f;@$a}
which is still reasonable...

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
