In defense of Fortran, as early as Fortran '66 (back in the bad old days of
punch cards, batch processing and paper print-outs), it was illegal to write
something like
ISGOOD .XOR. ISFREE .XOR. ISHERE
without parentheses, since it is not obvious how this expression was to be
evaluated.
I'm also glad that Ada does not accept
A ** B ** C
since I know programming languages that would evaluate this as
( A ** B ) ** C
as well as languages that would evaluate this as
A ** ( B ** C )
