something that occurred to me in the shower this morning...

we use $VERSION in perl to look for the version of the package.

gtk+ actually uses the macros  GTK_MAJOR_VERSION, GTK_MINOR_VERSION, 
and GTK_MICRO_VERSION to define the API against which you're compiling, 
and provides GTK_CHECK_VERSION() to check if that's new enough.

the upper-case versions are compile-time, the lower-case versions are 
runtime.

we could use this same convention in the bindings and avoid needing 
either new documentation or new perl-only API.


   # tell you what the bindings are compiled for
   $Gtk2::MAJOR_VERSION
   $Gtk2::MINOR_VERSION
   $Gtk2::MICRO_VERSION
   Gtk2->CHECK_VERSION

   # tell you what the current actual runtime versions are
   $Gtk2::major_version
   $Gtk2::minor_version
   $Gtk2::micro_version
   # note that this one has completely different semantics than 
CHECK_VERSION, even in the C API
   Gtk2->check_version
