I'd say an API like QVariant would then be useful:

if you call convert() and it can't convert, it'll silently fail. You'll get=
=20
the default value for the type (empty lists, null QStrings, 0 integers,=20
false, 0.0 for double, etc.).

But if you do that, it's your fault. You should have checked canConvert()=20
first.

You say now everything is a string, so the "canConvert()" to string is alwa=
ys=20
true. But a new backend could have different logic there.

=2D-=20
