is "exc" short for "exception"?
I typically see "exn" for that (not that it's much better, just spell it all
out).

[Martin Maly, 2011/02/04 01:02:34]

Done.

[Lasse Reichstein, 2011/02/03 12:10:41]

Just use
 assertUnreachable("did not throw exception")
here.

[Martin Maly, 2011/02/04 01:02:34]

Done.

The string looks unterminated. You are probably not getting the octal-escape
SyntaxError.

Perhaps make check for each argument to eval that it is not an error in
non-strict mode.

Why the nested functions?

[Martin Maly, 2011/02/04 01:02:34]

The nested functions exercise the lazy compilation. Strictly speaking the 4
levels are not necessary but it tests yet another facet of the code.
