Oh, I see what you mean. I confused you, sorry.
typeset_silent kicks in only when you do `typeset foo` and there is
already `foo` in scope. Here, when have `typeset USER` in a function,
there is no `USER` in scope, so a new parameter is defined.
I cannot offer a solution because I don't know what you are trying to
achieve. No small change will make this code look reasonable.
Roman.
