But how do external variables work? If I create a variable in the 
server(such as a class), can an html file access it easily? (not 
having to jump through hoops)


doctype html
html
	head
		title D string interpolations test
	body
		- import std.algorithm : min;
		p Four items ahead:
		- foreach( i; 0 .. 4 )
			- auto num = i+1;

		//- Unescaped output
		p Prints 8: !{ min(10, 2*6, 8) }


here, extvar is a int located somewhere else(other deit html file 
that has ran(hopefully) or vibe.d project that created it.

(Obviously there has to be a way to get extvar)

E.g., If deit can have a special variable called context that 
each html file can access and along with the vibe.d project, then 
we can easily pass the variable.

or whatever

I am a very new at this, but I think "the solution" is to call  
res.render! with all alias names you need.
Defining int extvar =... before; you use:

   res.render!("your-template.dt",extvar,..)

hope this helps. Regards mt.
