It is nonsensical to say without measuring. Humans are
notoriously bad at predicting performance issues. Wrap all your
hardworking code into a loop with like 100 iterations, compile
and run:

That always allocates. Only appending may avoid allocation:

But, I would instead use ranges if possible to avoid all allo

I've got a plug-in which is a shared library. Like this
module plugin;
@safe int VersionOfAPI()
{
return 1;
}
this is builds to plugin.so
in main.d I'm loading the plugin and bind the those functions
like so:
module app;
@safe:
alias apiverfn = int function();
apiverfn apiVersion;

Is it possible to convince the compiler to look the other way
while binding @safe functions from the plugin ?
It probably has nothing to do with @safe, but is because of the
