Answer / vinoth_bksys
The differences are many and often subtle:
* use only expects a bareword, require can take a
bareword or an expression
* use is evaluated at compile-time, require at run-time
* use implicitly calls the import method of the module
being loaded, require does not
* use excepts arguments in addition to the bareword (to
be passed to import), require does not
* use does not behave like a function (i.e can't be
called with parens, can't be used in an expression, etc),
whereas require does
