 Config::Extensions - hash lookup of which core extensions were built.

     use Config::Extensions '%Extensions';
     if ($Extensions{PerlIO::via}) {
         # This perl has PerlIO::via built
     }

 The Config::Extensions module provides a hash %Extensions containing all
 the core extensions that were enabled for this perl. The hash is keyed by
 extension name, with each entry having one of 3 possible values:

 dynamic
     The extension is dynamically linked

 nonxs
     The extension is pure perl, so doesn't need linking to the perl
     executable

 static
     The extension is statically linked to the perl binary

 As all values evaluate to true, a simple "if" test is good enough to
 determine whether an extension is present.

 All the data uses to generate the %Extensions hash is already present in
 the "Config" module, but not in such a convenient format to quickly
 reference.
