vibe.d diet - is there a way to use a D variable inside the "parameters" of a tag

[Chris Bare]

I'm trying to generate a list of buttons and insert the value 
programmatically.
Here's what I've tried:
		- foreach (i; ["Prev", "Replay", "Next"])
			input(type="button",value=#{i})
that does not compile.
if instead I use:
			input(#{i})
It compiles, but generates: <input #{i}>

Is there a way to double escape the variable, or is substitution 
just not supported there?
