Note that it's not uncommon for *installed* Python programs to have the
"direct form" of the shebang line pointing at the exact Python that
they're intended to use (especially when they need third-party libraries),
but that's installation-specific and shouldn't be used for distributed
"source" versions.

The env-style format can also use versioned names like 'python3' or
'python2.7'; it can be any valid Python command in the PATH.
Unfortunately it can't specify version ranges, though. :-)
