How to use word boundaries with RegMatch in Maple

Maple uses Henry Spencer's RegExp for regular expressions. Due to this you aren't able to use \b for word boundaries. Instead you should use [[:<:]] for the beginning of word boundaries and [[:>:]] for end of word boundaries. 

Some examples are below:

restart
with(StringTools):
test1:="these are words";
test2:="notwords";
test3:="words at the begining";
RegMatch("[[:<:]]words[[:>:]]",test1); #True
RegMatch("[[:<:]]words[[:>:]]",test2); #False
RegMatch("words[[:>:]]",test2); #True
RegMatch("[[:<:]]words",test2); #False
RegMatch("[[:<:]]words",test1); #True
RegMatch("[[:<:]]words[[:>:]]",test3); #True
RegMatch("^words[[:>:]]",test3); #True
RegMatch("^words[[:>:]]",test1); #False
