New Rule Suggestion / Rule amendment - in response to #903

In Issue #903 the rule in my opinion correctly throws on a += for simple defined arrays using the $var = @() method of defining an array to the var variable

I would suggest that a new rule is created that correctly identifies this method as being an expensive action and that a recommendation to use a fully defined Array collection would be a better suggestion, initially suggesting using a System.Collections.ArrayList

This rule should look for both @() & += and suggest converting these calls better scripting practices

Inizia leggendo l’issue #903 e la regola esistente che gestisce += per gli array. Determina come l’analizzatore dovrebbe riconoscere sia @() sia +=, quindi definisci la raccomandazione e i test necessari per confermare che vengano suggerite collezioni completamente definite, inizialmente System.Collections.ArrayList.
