Having to split and match seems slow(50%). Surely the regex
splitter and matcher can be combined? Sometimes we just need to
extract out and remove information simultaneously.
I propose a new function called extractor that returns the
matchAll and splitter's results but is optimized.
void foo()
{
void bar() { foo; }
switch
case: scope(exit) { do } break
bar;
}
fails to execute do
void foo()
{
void bar() { foo; }
switch
case: bar; do return;
bar;
}
does work... yet there is no difference except the scope exit.
In my code it is if do
When parsing an xml file I get #text for tagName on basically

Can dmd or ldc optimize the following cases:
foo(int x)
{
if (x > 10 && x < 100) bar1; else bar2;
}
...
for(int i = 23; i < 55; i++)
foo(i); // equivalent to calling bar1(i)
clearly i is within the range of the if in foo and so the checks
are unnecessary.

No, it's in an external thread(it is in a callback). All I can
think of is that something is happening in between the two checks

It is true that it is being used in a thread. It happens when I

The whole point of the check is to make sure X is not null but it
seems to be failing.
The debugger is showing X is not null
FieldNameTuple!T
std.traits.Fields!T
are non-empty when T is an interface!
An interface cannot contain fields and yet these return non-zero
and screws up my code. While I can filter for interfaces it makes
me wonder what else may slip through?
Is it a bug or what is going on?

we have to do

Why not
