Subject: bug#62452: 30.0.50; [PATCH] Avoid shadowing variables in some Eshell command forms
Date: Sat, 25 Mar 2023 21:48:13 -0700

[Message part 1 (text/plain, inline)]

To see this in action, start from "emacs -Q -f eshell", then:

  ~ $ setq value "hi there"
  hi there
  ~ $ echo $value
  hi there
  ~ $ echo ${echo $value}
  eshell-temp

The last command should *also* print "hi there", but the variable 
'value' gets shadowed by some internal Eshell code. (A similar problem 
occurs for 'for-items' when using a for loop in Eshell.)

Patch attached.
