> I'm not sure MessageFormat is a proper templating framework though: there
are no named parameters, so the template string would be awkward and it would
be hard to reason about :-/
Yes, I agree. MessageFormat might be hard to read, but
* it is better then my first implementation, which used `String#format`
which sucked even more ;)
* it can use formatting options for numbers, which is handy, as it allows
something like `{1,number,000}`
* other template languages might look like the JMeter built-in variable
replacement syntax or would have to be included (for the former I thought about
StringSubstitutor from commons-text)
Do you have a special templating system in mind, that we can/should use?
One idea would be to parse the format string and generate the three
placeholders à la `#{prefix} #{path} #{count,number,000}` -> `{0} {1}
{2,number,000}` via `s/#{count\b/{2/`, etc.
