I disagree.  Ternary logic (where there are three logical values true,
false and unknown) is NOT commonly understood by non-programmers.  Thus, I
don't think this is a good candidate for the default syntax.

However, it's easy to do with HTML::Template::Expr.  If you don't like
writing <tmpl_if expr="defined(foo)"> then just write a filter to change
"<tmpl_if_defined foo>" (or whatever you like) into it.
