No, that’s wrong. What mksh does here is:
• Save a pointer to the current “variable locality scope” as l_expand
• Create a new subscope called l_assign
• Evaluate “foo” inside l_expand, store as cp
• Assign cp to “a” inside l_assign
• Run “:” with l_assign “on top”
• Discard l_assign
• Now l_expand is “on top” again, as it was before we started.

What effects precisely?
Note that “exec” itself is a special builtin command, so
this may already answer your question ;-)

Sure, I’ll prod bonsaikitten later. Does Gentoo have a recent
(2.x) klibc packaged including the “klcc” compiler wrapper?
