She wants something like Tcl's [uplevel] command, most likely. http://www.tcl.tk/man/tcl8.6/TclCmd/uplevel.htm Short version: evaluate a command in the caller's scope, instead of in the function's scope. In Tcl, you can use this (WITH EXTREME CAUTION) to implement new commands with the semantic powers of "if" or "for". It makes "eval" look like a toy. Bash has nothing like this. Bash doesn't even come CLOSE to this. It was never designed for this. It's a SHELL. If she's using aliases to try to mimic this behavior, I have nothing more to say on this topic. Horse, beating.
