Redirection between assignment statement and command name prevents alias substitution

[Oğuz]

    $ alias u=uname
    $ >&2 a=b u
    Linux
    $ >&2 u
    Linux
    $ a=b >&2 u
    No command u found, did you mean:
    ...

In all three cases `u' is in a position where a command name may appear,
and should be subjected to alias substitution.

This is reproducible on devel too
