Re: Use and Require - making an informed choice.

Does the module need to be imported at compile time (i.e. does it rely on using BEGIN)?

Remove "(i.e. does it rely on using BEGIN)" as it isn't a factor.

The fact that a `use` creates a `BEGIN` block can matter if order of compilation is important. That's substantially different from a runtime `require` and `import` without the `BEGIN`. For example: importing a function that overrides a built-in. If requiring and installing a subroutine at runtime, the compiler will already have resolved calls to the built-in functions at compile time before the replacement functions are installed. -xdg Code written by xdg and posted on PerlMonks is public domain.
