I think it's worth mentioning that, right or wrong, postcodes are often
written without the space in the middle. Abigail didn't mention whether
he wanted to just match the canonical form, or match any common form.

No. This covers it:
/[ABCEGHJKLMNPRSTVXY][0-9][A-Z] [0-9][A-Z][0-9]/;
> Is there any checksum buildin?
LOL! More like a big collection of maps that changes every five years
with the census.
The space in the middle is required by Canada Post but if you're
accepting user input it's better to make it optional, as well as allow
lower case, and just reformat before using.

I'll probably make it so that people can do things like:
use Regexp::Common;
/$RE{zip}{British}/; # Uses ' ' as separator.
/$RE{zip}{British}{-sep => '\s*'}/; # Uses \s* as separator.
/(?i)$RE{zip}{British}/; # Case insensitive match.
