I understand that, but I'm arguing that that's a non-problem. Importing
sys is a regular thing in Python, not an exception. You need sys to get
to sys.argv, sys.exit, sys.stdout, etc. -- it's not like sys is an
infrequently used module. Since sys is always present, importing it is
not an efficiency problem, either.
mod = __import__(modname, submodule=True)
with
import sys
__import__(modname)
mod = sys.modules[modname]
"import sys" is normally located near the beginning of the file (and
needed by other things), so the actual code snippet would really contain
only those two lines, which don't strike me as bad. Ideally, __import__
would simply return the "tail" imported module in the first place, but I
don't think introducing a boolean keyword argument really improves the
design.
