Extend safe navigation operator for [] and []= with syntax sugar

Description

Now we have the safe navigation operator &.. But this cannot be used with syntax sugar form of the methods [] and []=, which are more frequent than their ordinary forms of method call. For example, when a can be either an array or nil, we can do:

a &.[](3)
a &.[]= 2, :foo

but we cannot do:

a &.[3]
a &.[2] = :foo

It would be nice if we can extend the use of &. to cover syntactic sugar as above.
