A Question regarding HTML_Template_Flexy if statements

Can I do a standard if $key = $value evaluation using the flexy if statement functionality? In the docs I just see that you can test to see if a variable, or function returns true/false. Can I test for instance if:foo=bar Thanks, BC This message may contain confidential and/or privileged information.
