Discussion Thread: DIP 1036--String Interpolation Tuple Literals--Community Review Round 2

[Walter Bright]

Comparing two simple examples of #DIP1036 and #DIP1027:

DIP1036:
   printf(i"%s${item} %02d${other_item}"); // metaprogramming + printf overload

DIP2027:
   printf(i"$item ${%02d}other_item");  // direct


DIP1036:
   writeln(i"I ate ${apples} apples and ${bananas} bananas totaling ${apples + 
bananas} fruit.");

DIP1027:
   writefln(i"I ate $apples apples and $bananas bananas totaling $(apples + 
bananas) fruit.");


DIP1036 is more user typing, including awkward-to-type { }, along with needing 
substantial user code to implement (for printf).

DIP1027's syntax is optimized to make the most common cases the simplest for the 
user, no user code is required.
