When two operators have the same precedence, left to right ordering is followed.
• If precedence does the wrong thing, or if it is unclear, use parentheses to bring out
the intended order of evaluation.
Example Interpreted as
1-4-2 ((1 upto 4) downto 2)
1234[]4321| ((1234 block 4321) palindrome)
1-4 block 4-1 ((1 upto 4) block (4 upto1))
(1-4|),(4-1|)| ((((1 upto 4) palindrome) concat ((4 upto 1) palindrome))
palindrome)
