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]'
