Forums Bug Reports incorrect value for $modespl

On irc.irchighway.net:
$modespl returns 15, but there is MODES=20

Edit: using /parseline to debug a bit shows that it looks like there is an hardcoded limit at 15, passing MODES=14 makes $modespl return 14, but with 16, it returns 15.

Thanks for your bug report. The reason for this is that mIRC applies a sanity check to some server-set values. In this case, 15 modes per line was considered a high enough value at the time. This will be changed in the next version to allow a higher value.

I'd suggest the sanity value be over 30 as I'm currently on a network that allows for 30 modes

I completely disagree, mIRC, or any IRC client here, should not change these kind of value given by IRC server. I just don't understand why there is a limit on this value, I would like to see this limit removed, not extended.
I don't understand why it's called a sanity check here, what's insane about accepting the value from the IRC server, even if it were super high like 4500? You can call this value non sense, you can easily argu that the IRC server shouldn't be using such a high value etc, but you should accept it.
Extend it to 30 today and tomorrow I'll report that my IRC server use 31 (unless there is a good reason for such a limit that I'm currently missing, of course).

I generally try to apply limits/validation/sanity checks on allowed values to be safe. Thanks for your comments everyone.
