The point here is not how to escape but that the regular way to do this,
i.e., pass your value thru a function, or write a macro that calls that
function; they just polute the template and makes the whole thing dificult
to read.
The need is for a mechanism that can perform this transformations implicitly
without having to call something everytime we type "${....}".
