Respectfully, Sebastian, I disagree.

Consider for example that several of the autoloadable functions in the
zsh distribution rely on "autoload colors".

If autoload behaved the way you suggest, this would break, because the
colors function would not be found at the absolute path from which the
calling function was loaded -- unless the writer of the calling function
has used "autoload -d", of course.  But if we're now relying on the
author to use the correct options for autoload, we're right back where
we started -- might as well rely on the author to make his function
suite "relocatable" by way of $function_source as well, and that is
now possible.

There's no magic solution that automatically covers all the variations
without cooperation from both the writer and the installer of the suite.
