perl -e 'print ((split("\\.", "a.b.c"))[0]);'
It's a bit tricky. The outermost braces belong to print(), the next
ones enclose the call to split() so that it can be sliced and the
innermost enclose the parameters for split(). Only the innermost may
be left out.
This makes the slicing of function result a bit clearer I think:
($hour, $minute, $sec) = (localtime())[2,1,0];
