What's the most suitable param type for generators?

Param
1

This raises an error:

ValueError: List parameter 'Test.gen' must be a list, not an object of <class 'generator'>.

import param

class Test(param.Parameterized):
    gen = param.List()

Test(gen=(i for i in range(0, 10)))
2

You could do:

class Test(param.Parameterized):
    gen = param.ClassSelector(class_=types.GeneratorType)

But generators are somewhat finicky so be careful using them.
