I fail to see why checking for closures makes variable access much

"compiled" to use the $ctx->path() method, and it already does quite
a few type checking logic already.
Checking for a closure basically would mean adding "instanceof"
conditions, being instanceof an operator and as such extremely fast,
I don't see why it should hurt overall performance.
First path of component is optimized to be $ctx->var which reads value
directly from a property of $ctx object. For simple cases like $
{variable} no function is called at all (not even __get()).
Without any extra syntax, it's not known at compilation time whether
variable will be real value or a closure, so I won't be able optimize
those checks away.
