Here's a message I sent to cpan-testers, but with the volume of
reports to that list, I doubt anyone on it has time left
from deleting the messages to respond.
I got one failure with 5.6.2 and passes with 5.8. The problem
appears to be the constant pragma, which doesn't seem to have an
independent contemporary existence on CPAN.
Module::CoreList tells me that it was 1.02 in 5.6, and 1.04 in
the 5.8.3 I developed my module on.
How do you find out what can be done in older perls?
The message to cpan-testers:
With reference to:
http://www.mail-archive.com/cpan-testers%40perl.org/msg398745.html
How do I go about finding out what the problem is here?

Because it is not failing on 5.8, I suspect that in 5.6.2 the constants pragma
didn't have:
Defining multiple constants at once
Instead of writing multiple "use constant" statements, you may define
multiple constants in a single statement by giving, instead of the con-
stant name, a reference to a hash where the keys are the names of the
constants to be defined. Obviously, all constants defined using this
method must have a single value.
use constant {
FOO => "A single value",
BAR => "This", "won’t", "work!", # Error!
};
Line 16 of my module is:
use constant {
C1 => 'C1',
C2 => 'C2',
and it continues on this way to line 40.
PREV => "PREV",
COLORS => "COLORS",
};
What do I do now? constants doesn't seem to have a contemporary
existence on CPAN distinct from perl.
