LexerError when nesting single quotes in Strings

[webnov8]

The compilation error: "error: Expecting COMMA, but got "'" (SINGLE_QUOTE) instead." is raised when using escaped single-quoted characters.

For example:

print '\''

Current workaround is to use a temp variable containing the single quote, like:

single = c'\''
print '[single]'

This is an interesting issue, but I'll give you an easier workaround:

print "\'"

The same sort of problem happens with:

print "\""

So as long as you don't need both quote marks within the same string, you should be okay. Obviously this problem needs to be fixed, but I thought you'd like to know about an easier workaround (at least it is in my opinion).

yeah i think you can also go double-single-double as in:

print "'"
}}
I just meant that other workaround for the general case where you do have a messier string, but thanks.

For reference, here is a regex for Python string lits:

I have put together a patch with some tests for this problem.
