Dear Heinrich Schuchardt,

Further we cannot first introduce a command call and then eliminate it due to backward compatibility. We should decide on the final version beforehand.
Full agreement. we need a concept of what is needed / wanted first. And then we should look how current vrsions of hush fit into this.
In the Linux world you can override a command using an alias. So I am not sure if a built in command should take precedence over a variable of the same name or the other way round.
This is simple. The PoLA (Principle of Least Astonishment) applies here. Behaviour must be the same as in other (to some extent POSIX compatible) shells. A shell should parse it's input, not adhoculate it.
Best regards,
