This newbie has a package that defines a fair number of (constant) messages using: 
package foo;
...
our $enqmsg = pack ("C*", 0x01, 0x55, 0x22 ...);

[download]
The "main" program then uses those messages in subroutine calls such as 
printmsg ($foo::enqmsg, ...);

[download]
Since many of these messages are used only once, I receive a great number of warnings about them only being used once. Is there something "suboptimal" about the way that I have structured this ? Or should I simply define an "extraneous" 
@msglist=($foo::enqmsg,...);

[download]
at the top of the program to force a second reference ? Is there anything that can be done in the defining package so as not to burden "users" of the package ? Thanks, Scott.
