I'm not sure such an addition would help much with the base
interpreter start up time though - most of the modules we bring in are
because we're actually using them for some reason.
It wouldn't. This would be for third-parties only.
such as hg. That is what I had in mind.
Would the following work? Treat a function as a 'loop' in that it may be
executed repeatedly. Treat 'import x' in a function as what it is, an
__import__ call plus a local assignment. Apply a version of the usual
optimization: put a sys.modules-based lazy import outside of the
function (at the top of the module?) and leave the local assignment "x =
sys.modules['x']" in the function. Change sys.modules.__delattr__ to
replace a module with a dummy, so the function will still work after a
deletion, as it does now.
