Benchmark?

[samdark]

Hello,

The package aspect-oriented concept is interesting. Have you conducted any benchmarks comparing it to usual inline validation?

Hello, I created some benchmark to check this.

Of course, it adds some time. But you can cache your parameters in case you want faster performance.

Thanks. There's a penalty, but in many cases it isn't critical.
