I disagre.  I think that if you evaluated all the FreeMarker templates =
out
there you would see a lot of ${something?if_exists} or
${something?default("")}.  The easy syntax isn't meant to address
${something?default("something else")}.

I like Daniel's idea of shorter syntax for =
${something?default("something
else")} but I certainly think that it doesn't mean that $!{something} =
isn't
useful.
