Agreed! It seems that the two best solutions (as I would call them)
bubbled up to the top immediately. I liked one because it was
built-in, and the other because the language was more set-oriented.<br>
<br>
It got me thinking about the following excerpt from the List::Util man
page, and how the comment "nice to have in the perl core, but..." isn't
really a big problem with Perl (because it's so easily extensible,
unlike the proprietary languages I work with).<br>

<code>"List::Util</code> contains a selection of subroutines that

expressed would be nice to have in the perl core, but the usage would
not really be high enough to warrant the use of a keyword, and the size
so small such that being individual extensions would be wasteful."<br>

for "for".<br>
