My favorite is probably the parser ignoring any valid redirection syntax with 
the special command substitutions.

 ~ $ { echo "$({xxxxxxxxxxxxxxxxxxxx}</dev/stdin)"; } <<<'hi'
hi
 ~ $ { echo "$(1111111111111111111111</dev/stdin)"; } <<<'hi'
hi

That one really is ignored. No variable named xxx... is actually set.
