[Feature request] Scroll style comments

[0qln]

Something like this:

/*\                                             /*\
|*|---------------------------------------------|*|
|*| generate the see score outside of the move  |*|
|*| generation and the sorting, such that it    |*|
|*| isn't computed for each comparison and when |*|
|*| don't break cache locality.                 |*|
|*|---------------------------------------------|*|
\*/                                             \*/

Bottom right needs to be handled differently in a few languages, i.e.:

• rust needs the last part to be \*/
• other c-style languages might need /*\*/
