in reply to Modules of Formats

I think the only real problem that you might encounter is copying the actual formats about. The problem is that there's no way of directly copying them unlike the other data types e.g
format foo = . { package mypkg; *form_foo = *main::foo; *form_ref = *form_foo{FORMAT}; } use Devel::Peek; Dump(*main::foo); Dump(*mypkg::form_foo); Dump(*mypkg::form_ref); __output__ SV = PVGV(0x80f9c78) at 0x8100de8 ... FORM = 0x80fd4e4 SV = PVGV(0x80f9dc0) at 0x8100e24 ... FORM = 0x80fd4e4 SV = PVGV(0x8101820) at 0x8100e3c ... FORM = 0x0
So you'll have to end up exporting entire globs into the given packages, which isn't ideal.


update: changed FORM to FORMAT

    In the year 2012-11-11 with the perl v5.12.2/v5.14.1 it does work

    $ perl 2>&1 |grep FORM FORM = 0x99aa4c FORM = 0x99aa4c FORM = 0x99aa4c

    Still doesn't quite work in v5.8.9

    FORM = 0x182fa08 FORM = 0x182fa08 FORM = 0x0
