Description

If x @ y appears in a script, it should be changed to x.__matmul__(y). This is used mostly by Numpy.

If you'd like to get fancy about it, you can also support __rmatmul__ and __imatmul__, but just the first one is enough for now.

Contributor guide

Research direction
Examine the pasteurize source code to see how other operators like + and * are transformed, then add a rule for the @ operator (matmul). Consider implementing matmul , rmatmul , and imatmul methods.
