Auto-delete auto-closed delimiters

[nekodjin]

From an implementation standpoint, the request is as follows: "Whenever a character is deleted, check if it forms an auto-closing delimiter pair with the antecedent character. If so, delete both."

Here's a concrete example: I type (. Helix detects that this is the first in an auto-closing delimiter pair, and therefore inserts the corresponding ) directly after my cursor. I hit backspace, which deletes the original ( character, but the automatically inserted ) character remains. This feature request requests that the automatically inserted ) should be deleted.

Revisiting this with an additional suggestion. When the first character of a delimiter pair is typed, if it would close a previously unclosed closing delimiter pair, it should not have the corresponding closing character inserted afterwards. For example: if my text looks like some | stuff), where | represents my cursor, and I type (, the corresponding ) should not be automatically inserted.
