Fixed it so: * We won't infinite loop in that place if we hit it again * We don't do the debug spam in the optimizer, unless the debug environment variable is turned on * We don't go sticking a raw integer into the AST on such constructs, which is what caused all the trouble in the first place Tests in integration/weird-errors.t.
