Could be worth trying to go throw list of loaded DLLs, shared objects in the
current process?
Araq, I think I can understand his intention:
He wants to use nre module only, if it is used by other foreign modules
already. Maybe to not unnecessary blow total executable size or to not
introduce more new dependencies. Maybe, he has the task to search for a
substring, so when nre is used alr
That's not how the import mechanism works, even if some other code imports
`nre`, it's not in your scope. You can check for `when declared(nre)` in your
code to see if you imported it on your own (if you have setup some complex
`include` files this can be useful).
In my module, I'd like to do something like
when defined(nre):
import nre
# code that works with regular expressions
so, if the user does
import nre
import my_module
then that code gets compiled, but if the user doesn't use nre, then we aren'
