More or less.
The following patch does the trick, but is not really elegant:

Note that there are other - although less bothering - limitations:
"""

File "<string>", line 1
1 and@ 2
^
SyntaxError: invalid syntax
"""
This should be catched by the lexer, not the parser (i.e. it should raise an
"Invalid token" error).
That's a limitation of the ad-hoc scanner.
