in reply to Was a module use'd or require'd?
IIUC the only distinction between use and require; import is the way they are triggered. Both perform OP_REQUIRE, but for use the parser calls Perl_utilize() in op.c, where a method call to import is faked, and the require and import calls are faked into a BEGIN block.
Other than inserting some hook right into Perl_utilize() and compile a development binary, I can see no way to reliably tell whether use Foo qw(bar) was called or BEGIN { require Foo; Foo->import qw(bar)}.
