How about
\score {
{ c d e }
\midi{ pre = \tempo 4. = 70 }
}
?
(I.e., \tempo is a music expression => it's not a grammatical exception)
Semantics: If pre is set, then embed main input in a SequentialMusic when
interpreting music for midi. So instead of interpreting { c d e } above, we
interpret the expression:
{ \tempo 4.=70 { c d e } }
