I'm not certain whether it does create conflicts or not in general,
but I think this particular example is flawed: ⍺ (f g h) ⍵ could be
anything depending on what name classes those symbols have
(particularly if g were an operator).  When f, g, and h are all
functions, then it's not a vector, but a syntax error.  No conflict
