feat: Support for non-unique capture group names. #180
Description
Request
Currently capture group names must be unique. Ideally, capture group names should be treated identically to variable names, supporting the same set of characters, and allow for repeated names.
Possible implementation
Refactor the code to allow for repeated capture group names:
- Take into consideration what it means if a variable name and a capture group name are identical.
- Take into consideration what it means the variable name of the variable containing the capture is identical to the capture group name.
- Take into consideration if a nested capture has the same name as its parent capture group. (Even though nested captures are buggy atm, this should still be considered to future proof the naming).
