Hello.
I'm new to D and I stumbled upon something strange about readf while writing
some test code.
The code:
import std.stream;
import std.stdio;
int main(char[][] args)
{
string input = "2abc";
auto memstream = new TArrayStream!(string)(input);
int x;
memstrea
Hello.
Consider this code
void main()
{
l:
{
int v;
}
v = 5; // ok, v is defined
}
As I understand from D's grammar this behaviour is not a bug as
LabeledStatement:
Identifier : NoScopeStatement
and NoScopeStatement in turn takes BlockStatement without creating new
scope.

My gut feeling is that the if statement's behavior is wrong and the

I agree, I think case with 'when' works as specs say.
No need for a rationale for what can be adequately

Hello, I'm having a bit of trouble with rdmd. rdmd puts the executable
in a temp folder, even with the --build-only option. Maybe this is a

Nope, there isn't :) In ordinary multitasking environment there is no guarantee
on upper bound.

hardware timer? In every OS? In every minor version of OS even? If not (and I'm
pretty sure it's not so), then you need to add more details. All about how
scheduler works. Or this precise talk on what happen after time is up would
just mislead people. Aside from the fact that sometime after time is up thread
would become runnable again (which is really obvious, no?) there is nothing to
say.

In _general_ case there is no safety in D. With all low-level capabilities one
can always defeat compiler. Removing intermediate-level safer (yet unsafe)
capabilities arguabily gains nothing but frustration. I'm all for encouraging
good practices, but this is different.

replace current dir with the dir where source is, but it will take
away control), but this works.
There is a bug though, I can't make it work with -Irelative_path_to_src. Looks
like .deps contain paths relative to where rdmd was ran, while dmd interprets
them as paths relative to where .deps file is.

One is fixed size array and other is dynamic. Honestly I doubt that it matters
for code generated by Ragel, since this is constant and won't be passed around.
If it's harder to make it fixed-size then don't bother.

s are directly embedded in
code.
In fact as long as you only access its elements (no passing array as an
argument, no assignment to another variable and no accessing .ptr) there is no
array object at all. If you do -- new object is created every time you do. I
believe Ragel doesn't generate code which passes tables around, so it doesn't
matter.
