can I use a snippet inside a snippet definition?

I would like to use a snippet inside a snippet definition.
For Example:

# javascript function
snippet fun "function (fun)"
function ${1:function_name} (${2:argument}) {
 ${0:// body...}
}
endsnippet

snippet def "reqiure.js define (js)" b
define(['${1:underscore}'], function(${2:_}) {
    #use javscript function snippet here somehow
    call_snippet fun
});
endsnippet
