|
||
grouping of arithmetic or logical operators by the compiler. Used esp. of
|
||
certain common coding errors in C due to the nonintuitively low precedence
|
||
levels of <b class="command">&</b>, <b class="command">|</b>, <b class="command">^</b>, <b class="command"><<</b>, and <b class="command">>></b> (for this reason, experienced C programmers
|
||
deliberately forget the language's <a href="../B/baroque.html"><i class="glossterm">baroque</i></a>
|
||
precedence hierarchy and parenthesize defensively). Can always be avoided
|
||
by suitable use of parentheses. <a href="../L/LISP.html"><i class="glossterm">LISP</i></a> fans enjoy
|
||
pointing out that this can't happen in <span class="emphasis"><em>their</em></span> favorite
|
||
language, which eschews precedence entirely, requiring one to use explicit
|
||
parentheses everywhere. See <a href="../A/aliasing-bug.html"><i class="glossterm">aliasing bug</i></a>,
