The special splitting version of the backquote construct
w = ` $split {cmds}
is equivalent to
oifs=$ifs ifs=$split {
w = `{ifs=$oifs oifs=() cmds}
}
but much more convenient.
It was added to 9atom in 2011, 9front in 2016, and plan9port
in 2025. At this point, 9legacy should just incorporate it.
It also gets close to my preferred syntax for no word splitting
at all: "{} from Inferno's sh becomes `''{}.
Cheers,
Anthony
