Atle Prange commented on CAMEL-1226:
------------------------------------

I have seen so many different ways of representing the placeholder, but 
why not use a java API standard.

Other examples are EL: #{0}, #{1}; StringFormat: %s, %s...

> Often one ends up with dsl expressions that build strings like:
> {code}
>  from("direct:start").to("ldap:localhost:" + port + "?base=" + query);
> {code}
> Would in not be better to write
> {code}
> from("direct:start").to("ldps:localhost:{1}?base={2}", port, query);
> {code}
> , where "{1}" means "the first argument in the string varargs following. ( "{1}" could of course be replaced by some expression that you like the format of)
> To implementent this one could overload the from() and to() methods to accept a vararg array of Strings following the uri argument, and interpolate the uri with the varargs...
