you can not. the smarty parser is regexp-based and very slim. it does
not do these syntactic checks. you'll notice that when you have errors
in your template (like a closing {/if} whithout an opening one). the
template-compiler does not raise an error, but the template has
php-syntax-errors.

so you'll have to maintain your own stack of myif-blocks and check
inside the myelse-function whats the top-open-myif it belongs to.
