Traceback when trying to parse `Position` verb #17

Open kalapi opened 1 year ago

kalapi commented 1 year ago

Fez code is as follows:

Feature cpsp {
    Position @cpspContext <2 0 4 0> <<latn/dflt>>;
};

or

Feature cpsp {
    Position @cpspContext <xPlacement=2  xAdvance=4> <<latn/dflt>>;
};

Traceback is:

I also tried the following just to test the syntax:

Feature kern {
    Position (A -60) V;
};

And i'm getting the following traceback:
