A collection of unrelated trivial functions. trim() is the same as String::Strip::StripLTSpace, only slow. trimArray() is a pointless specialisation, any method taking a list can also take a list of just one element, making the trim function superfluous. space() is the same as q( ) x $NUM, only slow. left() is the same as sprintf "%-$NUMs", only slow.
No parameter checks at all, I can see no reason to prefer this module over previous art or the built-ins.
