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.
Probably, but I would hate to force people to code in a specific way for
it to work.
The intent of what I proposed it to be transparent for imports within
functions. It would be a minor optimization if anything, but it would
mean that there is a lazy mechanism in place.
For top-level imports, unless *all* are made lazy, then there *must* be
some indication in the code of whether to make it lazy or not.
