True. Hoping not to wade back into the format-layer debate I watched go
by, nor rekindle the multiple-syntax idea, how about a preprocessor-like
facility so we can build things like this w/o making the language
bigger. For example :
<input type="text" name="email" value="#isNull($email, "")">
where
isNull(x,y) := #if (x) { x } #else { y }
A basic library of these will solve requests for things like $!var, and
people can extend it themselves.
And with caching, there should be no performance penalty.
I would volunteer to work on this, if it were deemed wanted.
