For +X only, this can be accomplished by
FPATH=/path/to autoload +X myfunc
Sebastian's plugin manager uses this.
} That doesn't do anything sensible at the moment --- relative paths to

If I understand what you're saying, that means
creates a function named "this/here/file" by loading "file" from
$^fpath/this/here ... yes?
And then (before this patch)
creates a function named "/this/here/file" from the same location?
So after this patch there is no way to autoload a function whose name
begins with a slash. Not that it was especially useful to be able to
do so, just confirming.
} autoload -Uz /path/to/myfunc
} defines myfunc to be found in the directory /path/to by reusing the
} filename element of the shfunc structure that's currently unused at this
} This seemed quite a useful feature.
Yes, this is specifically what Sebastian and (I think) Ray were asking
for several months ago.
If I may make a suggestion -- an equally useful variation would be for
autoload to search the $fpath at the time of the autoload command and
store the path where the file is found *iff* it is found. This would
be sort of like doing
autoload -Uz $^fpath/myfunc(N)
except that it handles the situation where $fpath does not yet contain
the "myfunc" file.
Another useful variation might be to fall back to the current fpath if
the function isn't found at the specified location.
