very interesting!

I would like to signal here that braces work too so:

* you avoid a fork
* you can have side effects in the tests

	if (x=34; true) echo -n 'tadaaaa: '; echo ${x:-NONE}
	if {x=34; true} echo -n 'tadaaaa: '; echo ${x:-NONE}

	tadaaaa: NONE
	tadaaaa: 34

To me this is weird because it means punctuations are not treated
the same way: \n ; | && || should be treated equally

in zsh (AFAIU) it's not consistant with the function declaration:

	foo() hostname && hostname
	echo tadaaaa:
	hostname

	# prometheus
	# tadaaaa:
	# prometheus

	if {true} hostname && hostname
	echo tadaaaa:

	# prometheus
	# prometheus
	# tadaaaa:
