import std.array : appender;
import std.stdio : writeln;
void main() {
auto app = appender!(char[]);
app.put('x');
auto foo = app.data;
app.clear; // done, start a new array
app.put('y');
writeln(foo);
}
This prints out 'y'. It's not surprising because what I suppose
app.data is doing is just returning a slice of the dynamic array.
Clear() resets the counter of current position. But this behavior
is confusing in practical use, IMHO.
Should calling clear in your opinion guarantee that a new array
gets allocated?
