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

One minute after I sent this I tried:
input(type="button",value=i)

and that works.

Yes. Just one thing to be aware of, if i is a boolean, then the behavior 
is to include "value" or not include "value" in the element.

In other words:

sometag(foo=true) => <sometag foo="foo"> (or something like that)
sometag(foo=false) => <sometag >

The only other annoying thing is that you can't use interpolations for 
classes directly using pug syntax, you have to use class attributes 
inside the parentheses.
