Oh. I just realized this happens a lot out here. Where I work, we
use scons, and each SConscript has a long list of filenames:
sourceFiles = [
#...many lines omitted...
It's a common mistake to leave off a comma, and then scons complains
that it can't find 'foo.cbar.c'. This is pretty bewildering behavior
even if you *are* a Python programmer, and not everyone here is.
