two cents in, Perl syntactic rules for prefixing $, @, % are
very consistent, IMHO: You just need to keep in mind the types of
the values/data types ultimately being expressed, and it should
become clearer. $ always prefixes

Paul, I would say it is your last \s+ which probably should be
written \s* which says there may or may not be whitespace after the last
number you find. With the plus there must be at least one white space.

You're quite right Ed, it's safer to copy the parameters at the start of a
subroutine. Behind the scenes the parameter values are passed by reference,
so modifying @_ directly will change the value used as the actual parameter
in the calling code. Copying 'my @params = @_' will give you a local
