When you say restrict to one each. Do you mean one for strings and one for
arrays?
If so I'd have to disagree with this, since having the same operation
available to both is less likely to give mistakes. Can you give an example
of an actual benefit for this? Since this would cause a backwards
incompatible change. I can't imagine many places if any use the curly
brackets for arrays or strings, but since it exists there may be people
using it. Changing the behaviour of this to only work for one of the two
options seems unnecessary in the name of making code slightly more apparent
on initial reading. But variable names and so on should be used to help
distinguish from array or strings anyway.
