// This is our virtual machine basic type. Reducing of expression will use this

// maintain lists on dynamically allocated computation values, and we won't have
// to cleanup if some error (divide by zero ?) occurs in the middle of a
// statement. String values are an exception since sdata will point to dynamic
// data, but since every step of the virtual machine reducing strings will free
// that data, cleanup will be automatic
