My favourite example of the need to use parentheses in LC is with URLs.

put URL "file:" & tVariable into temp

will attempt to put the URL "file:" into temp, and then append the 
contents of 'tVariable' to it, because 'URL' is a high-precedence 
operator. You need to do

put URL ("file:" & tVariable) into temp

to get the desired result.

FWIW, I fully agree - parentheses are very helpful to readability, and 
should be widely used.
