Hi,
I cannot use the definition of SIGRTMIN on ubuntu.
For following code I receive errors:
import core.sys.posix.time, core.sys.posix.signal,
core.sys.posix.stdlib, core.sys.posix.unistd;
import std.stdio;
alias SIG = SIGRTMIN;
void main()
{
writeln("Establishing handler for signal %d\n",
Thanks for all the above suggestions, but after many hour of

I've been thinking about scoped imports. While it seems like you
can use scoped imports a lot of the time, it seems like there are
some potential cases where you can't. Most notably if a function
input is a struct or class, then I can't figure out a way to use
a scoped import. This also applies

Yes, the reason is because the nested struct has a hidden member
- a pointer to its stack context. This allows it to access
variables from the surrounding local scope.

Thanks very much for all the help, your advice worked a treat.
One final question, originally I was defining the struct inside
