Per your wish, Eric, the glorious successor of Q() ... named M():
>>> def M(*vals):
... import sys
... import inspect
... caller = sys._getframe(1)
... call = inspect.stack()[1].code_context[0]
... _, call = call.split('M(')
... call = call.strip()[:-1]
... names = [name.strip() for name in call.split(',')]
... dct = {}
... for name in names:
... dct[name] = eval(name, globals(), caller.f_locals)
... return dct
...
>>> x, y, z = range(3)
>>> M(x, y, z)
{'x': 0, 'y': 1, 'z': 2}
OK, it's a little bit fragile in assuming the function must be called M
rather than trying to derive its name. And maybe my string version of
finding the several args could be made more robust. But anyone is welcome
to improve it, and the proof of concept shows that's all we need.
Basically, a "dict-builder from local names" is perfectly amenable to
writing as a Python function... and we don't need to inspect the underlying
source code the way I believe Alex' sorcery module does (other parts of it
might need that, but not this).
