I have classes like this one:

class SomeObject
{
    public function __construct($param1, $param2)
    {
       $this->process($param1, $param2);
    }
    ...
}

So I can instantly "call" it as some sort of global function just like

new SomeObject($arg1, $arg2);

which has the benefits of

• staying concise,
• being easy to understand,

but might break unwritten rules of semantics by not waiting till a method is called.

Should I continue to feel bad because of a bad practice, or there's really nothing to worry about?

Clarification:

• I do want an instance of the class.
• I do use internal methods of the class only.
• I initialize the object in the constructor, but call the "important" action-taker methods too.
• I am selfish in the light of these sentences.
