That's a weird thing to do. You call a function that returns the lines
of input as a list, in a context that joins them back together as words,
and then try to split the result on lines again.
lines already gives you what you want. Don't split.
perl6 -e 'for lines { say "<$_>"; }'
I am trying to test for something on each line.
Poop!
$ echo -e "abc\ndef\nghi" | perl6 -e 'for lines { say "<$_>"; }'
===SORRY!===
Function 'lines' needs parens to avoid gobbling block
at -e:1
------> for lines { say "<$_>"; }⏏<EOL>
Missing block (apparently claimed by 'lines')
at -e:1
------> for lines { say "<$_>"; }⏏<EOL>
Ahh, much better:
$ echo -e "abc\ndef\nghi" | perl6 -e 'for ( lines ) { say "<$_>"; }'
<abc>
<def>
<ghi>
