Version 6.2.1 (and previous) didn't preserve source locations for
identifiers in macros when the enclosing module is compiled to
bytecode.
The next release preserves them. I get
laptop% raco make /tmp/client.rkt
base-sig.rkt:10:22: thunk: unbound identifier in module
in: thunk
compilation context...:
/tmp/client.rkt
context...:
....
with the current development version (and DrRacket similarly provides a
source location).
