hi, thanks for bringing this up.
the alternate syntax has a rough past (if I remember correctly, [] was
mentioned to be deprecated, then with 5.3 the preference was switched:
[] is the preferred way now, and {} got almost deprecated), so if we
plan to support the {} syntax on long term, I'm +1 for adding this to
the language.
I we plan to remove it eventually, then imo it is better to not
introduce the support for the alternative syntax.
