how are the variables declared and what values do they have just prior

Some simpler examples:
$ perl6 -e 'my $x="abcde<br>"; say $x;'
abcde<br>
$ perl6 -e 'my $x="abcde"; my $y="$x" ~ "<br>"; say $y;'
abcde<br>
$ perl6 -e 'my $x="abcde"; my $y="$x<br>"; say $y;'
Type Str does not support associative indexing.
in block <unit> at -e line 1
$ perl6 -e 'my $x="abcde"; my $y="{$x}<br>"; say $y;'
abcde<br>
$ perl6 -e 'my $x="abcde"; my $y="$x\<br\>"; say $y;'
abcde<br>
So when is "<" and ">" a letter and when is it a redirect?

Hi Patrick,
Now it makes sense. It was trying to resolve a hash.
Thank you!
