bug#45576: 28.0.50 [native-comp] some functions in eshell stop functioning after commit 0593f478762437e2a8618f3f874a26424e4590b4

[address@hidden]

Hi,

More precisely, in this case, the "eshell-find-alias-function" definded in 
$EMACS_DIR/share/emacs/28.0.50/lisp/eshell/esh-cmd.el.gz seems where the issue 
pops up.

Before commit #0593f478762437e2a8618f3f874a26424e4590b4,

(eshell-find-alias-function "ls") shows

"eshell/ls"

but on or after commit #0593f478762437e2a8618f3f874a26424e4590b4, the same 
command shows

"nil"

Both cases are based on functions loaded from eshell.el.gz and esh-cmd.el's 
corresponding eln files.

It seems that some part of the type inference code added recently lead to this 
unexpected result.

Thanks,
Kiong-Ge.
