=head1 DESCRIPTION |
27
|
|
|
|
|
|
|
|
28
|
|
|
|
|
|
|
Retuning a simple C from many of the C |
29
|
|
|
|
|
|
|
methods often results in the loss of the overall context for that element. |
30
|
|
|
|
|
|
|
C provides an object that can be passed |
31
|
|
|
|
|
|
|
around which retains the overall context. |
32
|
|
|
|
|
|
|
|
33
|
|
|
|
|
|
|
For example, in C if the unmatched |
34
|
|
|
|
|
|
|
brace were returned by its C the containing |
35
|
|
|
|
|
|
|
C is likely to go out of scope, thus the C |
36
|
|
|
|
|
|
|
method no longer returns a valid location (rather it returns undef). |
37
|
|
|
|
|
|
|
Using the C preserves the C and the containing |
38
|
|
|
|
|
|
|
context. |
