3. Section 5.2 Bind. I understand that I can
option::unwrap(daynum("do")) to get back the uint.
What is the difference if I skip the bind keyword.
The llvm bitcode files that are generated w/ and w/o appear to be the
name.
The bind keyword here is redundant. Any time you have a function call
where one of the parameters is `_`, that's a bind. The only time that
bind is currently necessary is when you want to bind all the arguments.
In that case there's no way to discern that it's a bind without the keyword.
Sidenote: Is the item 'do' a joke amidst 'mo', 'tu', ... which appear
to be weekdays
'do' is the German abbreviation.
4. Suggesting a few edits
a) Section 8.6 - The map functions should read
vec::map([1, 2, 3], plus1);
b) Section 11, line 8 should declare acc mutable
let mut acc = "";
c) Similary, in section 13 Testing, the variable i must be mutable so
line 7 should read
let mut i = -100;
And again, I am feeling intimidated for posting this on dev mailing list.
Thanks. I checked in these fixes.
