Forums Feature Suggestions increase mirc's variable length limitation

Mirc's variable length limitation is 940 characters.

//set %temp $str(1,940)
(no error)

//set %temp $str(1,941)
* /set: line too long

//set %temp $str(1,950)
* String too long: $str

I also ran into this limitation with the length of a hash entry.

Is there any logic in this size limitation?
Can we PLEASE make it HEAPS longer?
