In my eagerness to see 'type select' go away, in formulating the proposed
plan, I forgot the potential need to retain 'type select' for a release
generating a warning in order to help transition users over in this step:

There are three possible approaches here:
1) retain existing behavior for 'type select' but have it generate a
warning saying that it's going away and that users should rewrite
to use 'select .type'
2) retain the parser's ability to see 'type select' but have it generate
an error and pull out all downstream code.
3) just pull the whole thing.
Typically, we've done #1 or #2 when changing features and that's probably
the high road to take. The lazy/impatient part of me would be tempted to
do #3, based on a sense that existing codes don't really use 'type select'
much, which the bug regarding having two type selects in a single program
would seem to suggest as well. But it's rare that the lazy/impatient side
of me is right. So #2 might be the right mix of helping people along
while also minimizing the amount of work required after the 1.11 release.
Or, if we propose the change on chapel-users, we could ask whether anyone
actually uses 'type select' and if nobody replies, potentially use that as
justification for #3 if we wanted my lazy/impatient side to win.
