Weakly against.

The subscript is a crossover between a function and a computed
property, and depending how you look at it, you will find either ":"
to be a better fit if you argue that they are closer to properties, or
that "->" is better, if you argue that subscripts are closer to
functions.  I don't find either argument to be more convincing that
the other, so I don't see a reason to change this part of the
language.

I wouldn't mind if the change would be made though, but I think by
changing subscripts to use colons we would end in the opposite, but
totally symmetrical situation compared to what we have now.
