Python inter-op

NOTE: this syntax is unstable and very likely to change before Hark v1.0, in particular, to permit qualified imports.

Python functions (or callables) are imported into a Hark program with import, with the following signature:

import(name, module, num_args);

• name: identifier, the name of the function to import
• module: identifier, module to import from
• num_args: int, number of arguments the function takes

For example:

import(foo, my_package.bar, 1);
