I want to add functions and procedures soon.  I should decide on syntax at least.

The args to a function are effective a struct, so I want it to look the same.
C doesn't allow "int a, b, c" in the parameters, which I think is clumsy.
struct can be

  struct name:
     a,b,c:number
     d:string

So function might be

   func name:
       arg1, arg2: type
       arg3: type2
   returns type
   do:
	stuff

A procedure is different as it doesn't have just a return type,
it has a return structure.  So many C functions have 'ret' or 'result'
variable that it might be nice to follow the Pascal approach of
assigning to the function name??  or having

    func name:
       args:types
    returns:
       results:types
    do:
       statements

A shorter version would be

    func name(args:types;args:types):type { }
or
    proc name(args:types;args:types):(result:type;...) {}
