Those both compile with 2.066

make sense?
Does it work?

Redundant? Not exactly.
__gshared makes it so that the variable is treated like a C variable - it's
not in TLS - but its _type_ is

No:

you're probably expecting should be

And I don't think it should, because the heap allocation that you're

because I would read it as constructing a pointer that points to the address

I agree. I'm trying to get a feel on the limits of this new
Paul:

Don't call exceptions errors, because in D there are also errors,
so they should have distinct names.
Is any shorter D way?
Perhaps not.

Hi,
I'm new to D and stumbled upon this very interesting discussion.
My question now is:
can you provide an example of how to return a collection of
homogeneous elements whose size is not known at compile time (for
wich you would normally use a dynamic array) from a function?
Thanks,
Marco
I get a failure on a test in format.d when I build my own project with
unittest. I though importing phobos header would not regenerate their
unittest modules.
Any idea of what can cause this issue? I already have reinstalled dmd
with visualD completely.

Thanks for the answer.
This is the bit of information I was missing: how to create an
array in the heap.
Is also this a valid way to do so?
int[] data = new int[0];
data ~= [4,2,3,1];

Update and clarification:
this triggers the error:
flight_info.add (Plot (ts.zip (vs), gfx, txt)
.color (blue*white)
.title (`velocity`)
, square (0.15)
);
this compiles:
flight_info.add (Plot (ts.zip (vs), gfx, txt), square (0.15));
this also compiles:
auto plot = Plot
I had not heard of this tool before. This looks like it's going
to be very handy, thank you!
I'd also like to note that elsewhere in my code (in a unittest to
be precise), I am using the full functionality of the Plot struct
with no hiccups...
info.add (
Plot (ℕ!24.map!(i = 0.8*i)
.map!(x = τ(x, sin (x^^2))),
