Note that since <function>return</function> is a language
|

construct and not a function, the parentheses surrounding its
|
||||
arguments are <emphasis>not</emphasis> required--in fact, it is
|
||||
more common to leave them out than to use them, although it
|
||||
doesn't matter one way or the other.
|
||||
arguments are <emphasis>only</emphasis> required if the argument
|
||||
contains an expression. It is common to leave them out while returning a variable.
