Sorry to be so "silly", but...

If my module get's conditionally require'd inside an eval() then the BEGIN block in my module won't be executed when the application starts it's execution which is what I'm trying to verify.

Update:
I read below: "...the moment it is completely defined ..." which corresponds to my understanding.

Doesn't this mean that an eval("require MyModule") will make sure that MyModule get's parsed in this very moment instead of during compilation of the main script?

If this is so, then any BEGIN block in MyModule will be parsed and executed at eval() time. No?

If this is not so, but all modules are parsed at compile time even if they are only conditionally required in an eval() statement, how can it be that modules that are not at all available on the system will not create a compilation error as long as the condition is not met and the module is not being actually required?

And how does perl handle when I read in from a database what module to conditionally require in an eval() statement?
(Where the name of the module does not ever appear in my code, but only in a variable brought in from the database.)


Everything went worng, just as foreseen.
