perhaps modules.  (e.g. import Text.Regex.Posix.Extended)

definitely modules for this one, because different engines might be provided by 
separate packages.

I suspect that most uses of regexes don't care much about the engine used, and 
one syntax covers most uses (e.g. extended regex.h, which is the default syntax 
used by Text.Regex).  So Text.Regex should be mapped to something like 
Text.Regex.Posix.Extended, with overloading to provide the =~ operator with 
[Char] or ByteString.
