You've done something wrong, then.
If you use <, {, (, or [, you match it up with its mirror image, >, }, ),
or ]. Any other NON-word NON-whitespace character can be used, and is
matched up with itself. If you use <>, {}, (), or [] for something like
s/// or tr///, you can use another set for the second half; in fact, you
can use a non-pairing set for the second half.
Here are a wealth of examples.
s%%%
s&&&
s()()
s(){}
s<>//
s[]!!
s,,,
s>>>
s()}}
Notice those last two examples. s>>> uses ">" as the delimiter, NOT "<".
That means that it's just like s/// -- you use the same character three
times. With s()}}, I've used () as the first pair, and so I'm allowed to
use another set for the second pair. I could have used a matching set,
but instead I used }, so I have to match it with }.
