I managed to reproduce one of the errors I was getting.
I specifically did not initialize $x. If I do, the
error goes away. In my code, I did a "say $x" and it
said $x had something in it. That is what threw me off

my Str $x;
if $x.starts-with( "[" ) &&
$x.contains( "]" )
{ say "Passed"; } else { say "Failed"; }

The function should just complain that the variable is
not initialized.
