No; alias expansion operates on shell words, and in that position on the command line "x" "=" and "y" are separate words because of assignment syntax rules. The new treatment of "typeset" as keyword extends this to global aliases and "typeset x=y". There's more to it than this because "=" and "y" are not subject to global alias expansion when they appear in "x=y" but that's the basic premise. } Or perhaps line 2 should have signaled an error. It's long-standing practice that you can create alias table entries for things that it's not actually possible to later interpret as aliases. This is especially true when assigning to the parameter as you did. Basically in this case the rule is that if you break it you get to keep the pieces. } Also, the 'alias -L' output for that alias won't work as the code } producing the output intended. There is no correct output possible in this instance, the alias command provides no way to escape the equal sign. I don't see any reasonable alternative except to add a csh-style alias command where the word and its expansion can be separate arguments. That still doesn't help with the assignment-syntax conflict.
