c.f. #73 for str.format which might be easier to build first.

test case:

if __name__ == '__main__':
    a = 10
    print(f"hello world: {a} number")

AST looks like this:

                           JoinedStr(
                                lineno=3,
                                col_offset=10,
                                end_lineno=3,
                                end_col_offset=36,
                                values=[
                                    Constant(lineno=3, col_offset=10, end_lineno=3, end_col_offset=36, value='hello world: ', kind=None),
                                    FormattedValue(
                                        lineno=3,
                                        col_offset=10,
                                        end_lineno=3,
                                        end_col_offset=36,
                                        value=Name(lineno=3, col_offset=26, end_lineno=3, end_col_offset=27, id='a', ctx=Load()),
                                        conversion=-1,
                                        format_spec=None,
                                    ),
                                    Constant(lineno=3, col_offset=10, end_lineno=3, end_col_offset=36, value=' number', kind=None),

I'll prioritize this tomorrow.

Awesome. If we can get this fixed, we can transpile py2many/pyrs itself into Rust - it wont compile, but adding transpiling of py2many as a test case (I have this roughly coded already) will add a lot more coverage preventing exceptions during transpilation.
