Then, for a specified function foo and an object obj, the statement

let bar = foo.bindArgs(1, 2);

Why can't Python's raw string literals end with a single backslash?
... Note: Workaround is to use adjacent literal concatentation. r"foo\bar\baz" "\\" (wrap in parens if ambiguous) will create a single literal at compile time, the first part of which is raw, and only the last tiny bit is non-raw, to allow the trailing backslash.
