Please use the optional ? assertion for option arguments instead of undefined union types. Ditto to other instances.

ok, but ? is only available for functions whose required parameters don't follow an optional one. Meaning, I can change it in isWildcard(), but not in parseNumber() (_shared.ts)

This change seems wrong. Instead, I think we should use non-null assertions for the values we pass to the input argument. Even if the input is null, the function should fail, which is what we want.
