The "creative use" being the assigning it to itself rather=20
than using 'our' or 'use vars' to mark it as not subject to=20
'used only once' warning?

Would writing if on one line:=20

     if ($^W) { $Config::IniFiles::VERSION =3D $Config::IniFiles::VERSION; }

Suffice to hide it from the pseudo-parser?
