Smarty came "before" PHP's use of {} in embedded quotes and the
aborted attempt to make that the string-as-array operator, I think.
There are only so many ASCII non-alphanumeric symbols available on the
keyboard.
When you need an opening/closing "pair" the options get very limited
indeed.
When < and > are already taken by HTML, and ( and ) are more common in
normal text, the choice of { and } is pretty much the obvious choice.
