| Subject: | Javascript boolean return values are not converted |
The last statement of the javascript code should be returned to Perl, but if the type of the last statement is boolean, this does not work.
A common example is when the last statement is a comparison like "1 == 1". Intuitively, this should return true, or 1, to Perl, but it returns undef. The problem is that the case of boolean return values is not taken care of in the XSUB wrapper JavaScript.xs, but I have included a patch file which solves the problem.
