If Algebraic/Variant could be recognized by the language it would give
some interesting possibilities, like Variant array literals:
auto array = [10, 2.0, "abc"];
types it as Algebraic!(int, double, string)[];
auto AA = [ "a" : 10, "b" : 2.0, 3 : "abc" ];
types it as Algebraic!(int, double, string)[Algebraic!(string, int)];
for example, that may be used to express JSON structures with literals only:
int x, y;
auto json = [
"x" : x,
"y" : y,
"colors" : [
[
r : 255,
g : 0,
b : 0
],
[
r : 0,
g : 0,
b : 255
]
]
]
