I'm no expert but I'll look into it. Unless someone else already
tried it, I want to investigate first if it's possible to create
a callable object w/o using 'def', which alters the name space and
(the thing we're interested to) needs an extra identation level.

At first sight, what we do now (at function creation time) is:
1) execute a function definition;
2) compile a function call, and save the resulting code object for later use.

I'm wondering if we can save one step, and use a python callable object.
