LuaRuntime.table interface prevents creating table with non-string keys

[kmike]

It is not possible to create a table from {1: "foo", 20: "bar"} dict using LuaRuntime.table(**kwargs) because in Python kwarg keys must be strings.

What do you think about adding a method like .table(args, kwargs) (not sure about its name)?

[scoder]

A new method .table_from(*args, **kwargs) could accept iterables and mappings (PyMapping_Check() can detect the latter). If you then want to create a Lua table from the keys of a Python dict, you could say "L.table_from(iter(dict))", i.e. pass an iterator instead of the mapping container.

I take pull requests, including documentation. :)

Could you please clarify what should .table_from(*args, **kwargs) do when

1. multiple arguments are passed;
2. keyword arguments are passed?

Do you mean .table_from(obj), or do you mean something similar to dict.update, or something else?

[scoder]

it would iterate over "args" and process each value separately as either mapping or iterable. Keyword arguments from "kwargs" will be added at the end as if they had been passed as a single dict. Any multiply provided keys will overwrite the previous values, so dict.update() is a good example.

This makes sense; I'll work on a PR.
