When you do:
"erasxeme.txt".IO.f
It will fail (before the .f even) on the .IO call because "erasxeme.txt"
does not exist. perl6 will then throw an exception when you try to use the
value of that failed call.
So, you need to not "use" the value of the failed .IO call:
if not $f.IO.f { say "$f not found" }
