[FR]: ord, chr, hex

[aryeh-looker]

What is the current behavior?

The canonical starlark implementation does not have these methods.

Describe the feature

Implementing the Python functions ord, chr, hex. At the moment, I don't see a way to do this code-points (ord) without a lookup table; but it's certainly possible. url_encode and url_decode could also be neat; e.g. becomes %20.

The starlark-go interpreter has them: https://github.com/google/starlark-go/pull/330/files#diff-660b1952587485a635bc71f18020e83d4bbda7a9bffa2127a1a3c8453cb6387dR46

% bazel run src/main/java/net/starlark/java/cmd:starlark
>> ord 
<stdin>:1:1: name 'ord' is not defined
>> hash('a')
97
>> hash('/')
47
% python3 -c "print(ord('a'), ord('/'))" 
97 47
