R-alpha: (minor?) S/R inconsistency: mode(unclass(terms(...)))

[Martin Maechler]

I just stumbled over the following :

  mode(utf <- unclass(tf <- terms( ~ (x + y + z)^2)))
  ## R:  "call"
  ## S:  "expression"

Don't know if/when this could be important.
It made a big difference for me, but this was in low-level
experimentation...
