ah, the thing that now got the official commit: "stop after N errors".
just make the compiler stop after exactly one error, and most "strange"
error messages will go away.

somehow Walter can't accept that after emiting the first error compiler
is in undefined state, and trying to pretend that it is in well-defined
state or guess what well-defined state must be is a nonsense.

D compiler is fast enough to stop that horrible "now you have
100500 errors reported, enjoy" practice.

the second thing that i want to have is compiler explaining why it
rejected some templates. i.e. what constrains failed. those messages
about "can't instantiate" are among the most noisy and cryptic ones.
