Nobody except Khaled can know for sure, but I too think it's not going to happen. A .prop is a much better (and plausible) idea.
In the meantime, if you're interested in a scripted solution, you may find this handy:
alias gettokn {
var %c = \x $+ $base($3,10,16,2)
returnex $remove($gettok($regsubex($1,/(?<=^| %c )(?=$| %c )/gx,$lf),$2,$3),$lf)
}
It works exactly the same way as $gettok() except it supports null tokens. The only catch is that it won't work correctly if the input string contains linefeed (ASCII 10) characters, quite unlikely with strings meant for IRC. Adding support for LF while preserving the original functionality would slow down the alias (because it would have to be more complex). It's not worth it imo, considering the rarity of the cases where LF is present in the input.
