It is merely an alternative interface to the regex algorithms (though it
could probably be retargetted to the string algorithms library).
It's just syntactic sugar and I'm not quite sure about the overall Boost
regard for the use of operator overloading in non-arithmetic ways. The use of
+ for string concatenation in the standard library is often cited by
opponents of operator overloading because it deviates from the meaning of +,
and the same could be said for the use of << and >> as streaming operators.
That said, if the Boost consensus is that operator overloading is indeed not
harmful, even when the overloads have very different meanings (the Spirit
parser comes to mind), then I believe that perlish should be included as an
optional layer on top of either regex or the string algorithms library.
Similar syntax has worked very well for Perl and sed for quite a while, why
not give C++ programmers the same option?
