Parse issue

```
The following is valid tikz:
\begin{tikzpicture}
\draw (4,0)-- (20:6 -| 14,0);
\end{tikzpicture}

However, it produces the following error message:
Couldn't parse code. MismatchedTokenException: Expected token ')'. Instead 
found "20" which is of type INT in line 2 at position 15.
```
