Importing static readonly fields, static methods, and events are supported,
while static properties are not (see
https://github.com/IronLanguages/main/blob/master/Languages/IronPython/IronPython/Runtime/Importer.cs#L798).
A static class's field, methods, and events map nicely onto Python's module
variables and module functions. What would static properties map to on a Python
module? Python new-style classes have properties, but I don't know of a Python
construct on modules that would make to a property.
Help me understand your expectations, when would you expect
get_SomeStaticProperty to be invoked?
// C#
class x {
static int SomeStaticProperty { get { return new System.Random().Next();
} }
}
# property import (doesn't work today)
from x import SomeStaticProperty
print SomeStaticProperty
print SomeStaticProperty
If we chose to map .NET property imports to module variables, then we'd have to
execute the getter when imported, which would break this example (random
numbers). We could do some magic of exposing the PropertyInfo itself as the
variable, making an getter call look like:
SomeStaticProperty()
... and a setter call look like:
SomeStaticProperty(val)
Thoughts?
