Is there an easy way to get the string representation of an array, as would be printed by writeln(), but captured in a string? |

struct Foo {
int x;
}
void main() {
Foo[] data = [Foo(1), Foo(2), Foo(3)];
import std.conv : text;
import std.stdio;
writeln(data.text);
}
---
[Foo(1), Foo(2), Foo(3)]

import std.conv : to;
writeln(data.to!string);

.text is essentially short hand, that's all. I use it as it is more descriptive as to my intention.

if you consider this as a property, it makes alot of sense the var.propName syntax.
