We're clearly not talking about the same thing. Which shell doesn't
logically prepend the alias value to the current input and restart the
scan at the beginning of that new input string? I mean, you said it
yourself:
"all known
implementations stack the alias replacement to the input and re-call the
lexer."
Or are we hung up on the word "stack"?
