So I dug up Andrei's thread that mentioned something about properties
that hasn't been discussed as of recent: expensive copy semantics.

No. When porting C, C++, Java or C# code just search "//" and
In fact final switch can be an improved computed GOTO :)
Same for me, it breaks compatibility with C.
Also, i found the ocaml floating point operators (./ .+ .- .*) painful when
i had to use them.

I was browsing the Python spec yesterday and came across this interesting and
useful syntax:
"/" (one slash) means floating point division, e.g. 5/2 = 2.5 even though 5 and
2 are integers
"//" (two slashes) means integer (floor) division, e.g. 5.0//2.0 = 2.0 even
though 5.0 and 2.0 are floats.

For the low-level programmer, sometimes you must use switch because virtual
functions are more expensive (cache usage...) and pointers to functions too.
The problem is that even if the optimizer turn the switch into a jump-table, it
has generally no clue about whether the value will be in the ri

Hello,
D's array slicing is basically "an array means to specify a subarray of it. An
array slice does not copy the data, it is only another reference to it."
This definition, however, is easily violated by instance reallocation such as
changing its length:
int[] a = [0, 1, 2];
int[] b = a[0..
52 matches
