We found that the following "macros" generated loops that hid a
surrounding NIL block:
DO-SYMBOLS et al
lots of compiler transformations (e.g., that turned a map
into a loop)
Also, of course, plenty of macros written by users can inadvertently
cause the problem.
The simplest way around is to only generate TAGBODYs. Even PROG
establishes a NIL block.
