Then you weren't at Tony's Turing Award lecture:
"...I adopted certain basic principles [of language design] which I believe
to be as valid today as they were then...(4) The forth principle was that
the compiler should use only a single pass....I can still recommend
single-pass top-down recursive descent both as an implementation method and
as a design principle for a programming language. [Note carefully the next
sentance.] First, we certainly want programs to be read by _people_ and
people prefer to read things once in a single pass."
That last line is exactly what Robert was refering to: design the language
so that it can be read by _humans_ in a single pass (even if it isn't
compiled that way), because that's what humans prefer to do.
If only the rest of Tony's lecture were that favorable toward Ada...
