I don't fully understand what you're doing, but functions can
easily be turned into delegates using std.functional.toDelegate
[1]:
import std.functional : t
is there a way to convert a string representing a time (without date) to a
time, eg:
auto t = "19:03:40.143656";
auto a=SysTime.fromTimeString(t); // doesn't exist
My current workaround is to append a dummy date before and then
calling SysTime.fromSimpleString.
Is there a better way? seems need

Keep in mind that those instances are *static* and probably not
what you expect; modifying a will be seen across all instances of
Baa unless you actually assign it
Are static constructors guaranteed to run if the module is
imported? Also are static constructors in templated types
guaranteed to run for every instantiation? Even if the
instantiation is never actually used outside of compile time
code, like in an alias or in a UDA?
Imaginary code:
class Foo { }
class Baa {
Foo a = new Foo();
Foo b = new Foo();
Foo[] l = [a,b];
}
What should I use instead of to it work? Array!Foo(a,b) didn't
worked either.
I know this works:
class Baa {
Foo a = new Foo();
Foo b = new Foo();
Foo[] l;
this() {
l = [a,b];
}
