I've added a whole lot of string stuff, so that a repeat op can work.

Having no output from a test is bad, as it is indistinguishable from a
segfault (although the suite might note this now). Also we'll want to
be very careful about testing PerlUndef once we've added warnings in.
Alex Gough
In general I expect that a PerlString will be turned into
a string constant then loaded into a PythonString by code that knows what
it's doing. After all, we need to do something simillar when passing
SVs into C code at the moment, and I'm sure Inline::* will provide not
