24.3.50; eshell: variable `name' treated different from other variables |

Dear Emacs developers,
eshell treats a variable named `name' different than a variable
named `foo' (or any(?) other name):
How to reproduce:
emacs -Q -nw -f eshell
#now type
for foo in * { echo "$foo" }
# this lists the directory Emacs was started in
#now type
for name in * { echo "$name" }
# this instead lists as many times 'name' as the above
# for statement listed objects in the directory.
E.g.:
~/src/emacs/doc $ for foo in * { echo "$foo" }
Emacs/
lispintro/
lispref/
man/
misc/
~/src/emacs/doc $ for name in * { echo "$name" }
name
name
name
name
name
~/src/emacs/doc $
This is the case with
GNU Emacs 24.3.50.1 (i486-pc-linux-gnu, X toolkit, Xaw scroll
bars) of 2013-08-31 on dex, modified by Debian
and with
GNU Emacs 23.4.1 (i486-pc-linux-gnu, X toolkit, Xaw3d scroll
bars) of 2013-07-01 on binet, modified by Debian
Is this a bug?
Thanks, Gregor

Cool, indeed. I moved the file, added a test to catch this bug, and
changed Eshell to use lexical-binding.
