A different and much less invasive way to get the first 90% of this is
to pick an otherwise unused metacharacter (e.g. @) and use it as a tag
meaning "search for the rest of this on $PATH", the same way ~ is a
tag that means "find this name by starting in $HOME".

Then you just write @foo/ls or @bar/ls. You could also extend it to
work on arguments as well as command names, though you'd probably want
it to use a different search path variable.
