ATS has record types which are like tuples but each item is referenced via a name. They closely approximate C structs and in the generated C code are represented in this way. The following uses a record to hold x and y values representing a point on a 2D plane: fun print_point (p: @{x= int, y= int}): void = printf("%d@%d\n",... more →

ATS allows overloading of functions where the function that is called is selected based on number of arguments and the type of the arguments. The following example shows overloading based on type to provide a generic print function: symintr myprint fun myprint_integer (a: int) = printf("%d\n", @(a)) fun myprint_double (a: double) = printf("%f\n", @(a)) fun myprint_string (a: string) = printf("%s\n",... more →
