#
# naive - generate a regular expression that will lex regular expressions
# it is naive in the sense that it can't lex certain patterns, such as a
# pattern that contains nested parentheses (e.g. /ab(?:cd(?ef)?gh)+ij/ )
#
# The emitted regular expression is the default pattern that Regexp::Assemble
# uses to pick apart a string into tokens suitable for being assembled. If it
# isn't sufficiently sophisticated, you will have to supply your own lexer.
