Perl 6
Features to add once Rakudo implements them
- 100 doors (and possibly elsewhere): There's gotta be a better way to say
@squares[1 .. @squares.end]
, possibly usingWhatever
or a negative number in the subscript. Maybe I should just lobby for the inclusion of Haskell'stail
in the setting library. - Arithmetic Evaluator:
- Use
make
to create a much more digestible parse tree. -
my grammar
. I'm not certain you're supposed to be able to do that, but I think so.
- Use
- Comments: Nested bracketing characters.
- Creating a Function:
- Not quite the same thing (see Synopsis 2): <lang perl6>sub multiply (Int $a, Int $b) as Int { $a * $b }</lang>
-
&multiply = [*];
-
&multiply = &infix<*>;
- Monty Hall simulation:
-
:delete
adverb. - More trials.
-
- Trigonometric Functions: The base-switching interface specified in
Numeric.pod
.
