`sl` doesn't work as i had hoped if left-hand side indexes

[bjarthur]

i would rather sl in the example below step into foo, and it does precisely that if line 3 of bar has y instead of y[2] in the LHS. is this the intended before, or a bug? is there a command to step into foo? thanks.

foo (generic function with 1 method)

julia> function bar(x)
       y=1:3
       y[2] = foo(x[3])
       return y.+1

y[2] is a function call that occurs later than the rest which is why that get picked. I guess sl could be special cased to ignore setindex!.
