Do you mean the bug if the locale is using ',' as decimal delimiter ?

Fixed - see below...

Mhhh, this works because there is no PATH lookup required to find the
matching command...

The idea was to rename the PATH variable (e.g. via $ typeset -m ... #)
to something like "saved_path" and later do a $ PATH="${saved_path}"
"${cmd}" "$@" # which would have a similar effect...
... but your solution is shorter (and works since "sleep" is not bound
to a specific PATH element).
