There's not a reparse, but a single parse. While perl is parsing your source file, as soon as it finishes parsing a BEGIN routine, it executes it immediately before continuing to parse the rest of the code.

the module ... uses many, many constants in its implementation

Sounds like you could take advantage of use constant, see constant.

Count how many BEGIN routines you have in your source. I bet it's ~74. If your program really is spending 20% of its run time executing those BEGIN routines, then you need to decide if that's an important 20% or not. :-) If it is, then maybe you could gain some advantage by coelescing the BEGIN routines or converting them to some other form
