Detecting whether something holds in an array is the job of grep:
my $numbers = grep /\A$RE{num}{real}\z/, @data;
next unless $numbers == @data;
Alternative:
die if grep !/\A$RE{num}{real}\z/, @data;
my $numbers = scalar @data;

Interesting,
I see from your regexp you use a \A and \z, from Perldoc this means:
\A Match only at beginning of string
\z Match only at end of string
I am not sure I understand this requirement?
^ and $ depend on flags,

=~ /$RE {num}{real}/;
Does the regexp know to evaluate each element in the array implicitly? Or do I
need to tell it this?
Thanks so much!

Is foo10bar valid? /^$RE{num}{real}$/ says no, but /$RE{num}{real}/
says yes.

Chas,
Sorry but I am not clear on what you mean by reduce? Do you mean
remove all non numbers from the array?
snip
Sort of, the code doesn't modify the original array, it creates a new
array with only the values that are numbers.
