The use of braces is part of Perl variable expansion.  It does not
directly have anything to do with regular expressions, which is why
it is not implemented.  The approach taken in jakarta-oro's Perl5
regular expression implementation has generally been to only include
those features that strictly have to do with Perl regular expressions
and not the Perl scripting/shell language.  This becomes complicated
by the fact that certain features having to do with saved group 
interpolations and special variables intersect with regular expression
functionality despite not being part of the regular expression grammar.
If there's enough of a clamor for a feature that is part of the
Perl language and not the regular expression grammar, it tends to
get added.  Afterall, the point of the software is to meet developer
requirements.  So, is there a clamor for ${foo} interpolated group
variable expansion?
