Since it appears that unfortunately compiling script is not very feasible as someone from FMI said, maybe we could at least get compiled calcs & functions (perhaps not recursive ones, nor those with evaluate, if that's not possible).
So the filemaker would contain a compiled form of the functions and calcs, that would be compiled when saving the calc or function. As this is a finite, relatively low volume data, it won't add a lot.
This would speed up a lot of thinks, even conditional formatting
P.S: That's assuming they're not already compiled (but that would astonish me)
