Templates inside template parameters, e.g. {{foo|{{bar}}}}, don't work, the parser sees the first }} as ending foo.
Created attachment 77 [details] patch
Templates within templates like {{foo{{bar}}}} don't work, either. The regex that replaces templates doesn't balance the braces. Before doing something like in the attached patch, we should make sure: 1) it's useful - I'm not sure there's any reason to make the code more complex 2) it doesn't hurt performance
Templates within template arguments are defintely useful. The more templates like infoboxes that are created, the more useful this becomes. One example: A template for geographical coordinates (generating an uniform look as well as a link to a map) cannot be used in templates for geographical locations :( If there is a problem with syntax/parsing, then perhaps we can some special ugly syntax for this case. Since 3 brackets is already used for arguments, why not go to 4? E.g: {{foo{{{{bar}}}}}}
That said, I it seems strange from a syntax point of view why templates as template arguments cannot be handled, when template arguments (which also contain braces) can (for instance when using a template in another template definition).
In response to comment 0 Hallo! The first }} should be seen as the end of the template started with the last {{. Implementing this would solve bug 895 and would help for bug 2148. Regards Reinhardt [[user:gangleri]]

Probably related to this, "{{localurle:{{ns:4}}:Requested articles}}" don't work under 1.5 (they did under 1.4). The parser outputs "{{localurle:Astro73:Requested articles}}" (HTML) on my private wiki (the meta namespace is "Astro73").
testcase from http://eo.wikipedia.org/w/index.php?title=Ap%C5%9Deronsk&oldid=310604 {{Rusia urbo 2|Apsxeronsk||[[Krasnodara regiono]]|[[Apsxeronska distrikto de Krasnodara regiono|Apsxeronska]]|[[1863]]|[[1947]]|{{Koordinatoj gm|44|28|N|39|45|E}}|39,6 (2003)|03205501|86152|0}} behaves differently then the first example at http://test.leuksman.com/view/Ap%C5%9Deronsk Note: I will recommend the usage of distinct paramters for geographical coordinates for this template at [[eo:]]. Regards Reinhardt [[user:gangleri]]
Fix for 3526 should have fixed this
changed to worksforme http://yi.wiktionary.org/wiki/%D7%B0%D7%A2%D7%A8%D7%91 includes templates in templates at two levels Thanks for fixing this. Best regards reinhardt [[user:gangleri]]
