I understood your question different from what Dennis answered.
At least I was confused by similar lines, when I was a beginner
and did not know much about template constraints. What I would
have needed to know at that time is, that template constraints
limit the situations, where the template can be used. Here for
example, this destroy template can only be used, when the type T
is neither struct, interface nor class (these three have separate
instances, probably because they need different treatment) and
it's also not a static array, for unknown reasons.
What I don't understand is the 4th version with two extra
parameters. Here the documentation lacks an explanation, what
this is good for.
