SYNOPSIS
	closure symbol_function(symbol arg)
	closure symbol_function(string arg)
	closure symbol_function(string arg, object|string ob)

DESCRIPTION
	Constructs a lfun closure, efun closure or operator closure
	from the first arg (string or symbol). For lfuns, the second
	arg is the object that the lfun belongs to, specified by
        the object itself or by its name (the object will be loaded
        in the second case)

        Private lfuns can never be accessed this way, static and
        protected lfuns only if <ob> is the current object.

EXAMPLES
	symbol_function("efun::users")		-> #'users
	symbol_function("QueryProp", other_obj)	-> other_obj->QueryProp()
