As of 5.10, use constant will use less memory than Greg's version.
I'm loathe to make the same changes for 5.8.9, as the implementation
confuses some modules that inspect the symbol table. The necessary

Mmh. I see constant.pm does very little.
Well, it nicely sets things up for the compiler to optimize.

Let me know if this works ok for you.
1.14 reports v5.8.0 if use constant { ... } is in and v5.6.0 if
it is out.
So it works.

I got one failure with 5.6.2 and passes with 5.8. The problem
