  This is strange, because it is internally set as a float-only:

mbarbon@cheshirecat:$ perl -MWx -MDevel::Peek -e 'Dump $Wx::wxVERSION'
SV = NV(0x536d90) at 0x53fad0
  REFCNT = 1
  FLAGS = (NOK,pNOK)
  NV = 2.009

  So wxPerl never sets it as a string (for those not familiar
with Perl internals, the scalar on has a floating point part
(NV) and only the NV-part-OK flags (NOK, pNOK) are set).

  If you compare numbers as strings you are going to have
more troubles.
