I don't know what you mean. Please supply concrete examples.
Q: O Great Rabbi, Perl has so many precedence laws I feel I shall never
learn them all. Which is the most important of these commandments?
A: As it was in the beginning, is now, and ever shall be, the First
Commandment is the Law of Algebraic Precedence:
#1 MULTIPLICATIVE OPERATORS BIND MORE TIGHTLY THAN ADDITIVE ONES.
The Second Commandment is to think of those who come after you,
most preferably before they do so:
#2 DON'T BE A DAMNED FOOL: OTHERWISE USE PARENTHESES!
Follow these two Commandments and all the days of your life will be
blessed, for your code shall be ever right[eous] and all shall love
you for it.
Happy Easter, and good night. :)
