WebCilk is very faithful to C - indeed, a properly written Cilk program will turn into a C program with acceptable, serial execution if all Cilk keywords are erased. This is extended to function calls - the spawn keyword can only be applied to Cilk functions, and Cilk functions cannot be called by normal means, instead requiring a spawn.
