Thanks! Wish there was a less redundant syntax for the arrays.
Do you really need to write literal Value arrays? If not, you would
build a Value[] at runtime without seeing the syntax above.
Still, here is a function template that provides better syntax:
Value[] valueArray(Args...)(Args args) {
Value[] result;
foreach (arg; args) {
result ~= Value(arg);
}
return result;
}
void main() {
printValue(valueArray(4.5, "hello", 42));
}

Hi everyone!
What's the syntax for passing an array of Algebraics?
definition:
class None {}
class Value = Algebraic!(int, double, string, None);
That should be 'alias' instead of 'class':
import std.variant;
import std.stdio;
class None {}
alias Value = Algebraic!(int, double, string, None);
void printValue(Value[] values) {
foreach(value; values) {
value.writeln;
}
}
void main() {
printValue([Value(4.5), Value("hello"), Value(42)]);
}

Array of Algebraic argument syntax
Hi everyone!
What's the syntax for passing an array of Algebraics?
definition:
class None {}
class Value = Algebraic!(int, double, string, None);
void printValue(Value[] values) {
foreach(value; values) {
value.writeln;
}
}
usage attempts:
printValue([4.5]);
printValue(Value[4.5]);
printValue(Value[](4.5));
