what are the limits to CI's template parser?

What are the limits for the parser in CI? I'm currently using smarty, but I think it's way too much for me. I want something light and fast, but I also want to use a parser instead of php views.

Currently I'm only using:
File Includes
Variables
If/else statements
for loops


So far from reading the CI parser library, I only saw it supports variables and a basic for loop. Are there any extras to the CI parser? I'm trying not to include any external libraries, I prefer to keep things within CI.

You could extend the Template class or look into others work, like this: http://ellislab.com/forums/viewthread/68878/P45/#744970 (edit: which seems dead unfortunately)
