I quite strongly agree.
The DIP does not show any real improvements. The rationale mentions "few drawbacks" but then does not mention those actual drawbacks, so people can judge whether they are few or not.
The DIP show this example as an improvement:
myObj.myFn($medium, $square, $undefined);
Is the height medium?, the location the town square?, the shape undefined?
This is the "worse" version:
myObj.myFn(Size.medium, Shape.square, State.undefined);
Code will be read much more often than it is written.
Please give a real world example where really the enum name is so long and tedious that reading it is worse than without (and where
with does not solve the problem).
Indeed. This DIP goes also in direct contradiction to the named parameter DIP, which strives to make the code more explicit, with naming the parameter. This thing would then require for readability to call like that:
myObj.myFn(Size: $medium, Shape: $square, State: $undefined);
Besides tooling, also take into account someone relatively unfamiliar with D, stumbling upon a
$. (now what the heck is this gratuitous obfuscation?)
Making D as "readable" as Perl. :-)
