I've ask this question a couple of days before but I didn't get any respons=
e=20
[1]. I think this may be a bug.


If I define a shell function like this one:

  do_print() {
    print "__${NAME}__"  # print environment variable "NAME"
  }

and later call the function while setting the environment variable "NAME"

  NAME=3D"hello" do_print

the output is "__hello__" as everybody would expect. But if the function is=
=20
called this way

  NAME=3D"hello"                    # set NAME (no export)
  NAME=3D"::${NAME}::" do_print     # export something as NAME containing $=
NAME

the output is "__::::__" instead of "__::hello::__". If the same think is d=
one=20
using a command instead of a shell function the output is "__::hello::__".=
=20
Refer to the older email [1] for a listing of different test cases.
