<style> BODY { font-family:Arial, Helvetica, sans-serif;font-size:12px; }</style>Aah, right. Class methods I have used in past projects, but my understanding is that, in these instances, Self can still be accessed, but represents the class rather than the object, can be called without an instantiated object, and still have the issues that they can be virtual and overridden (something i'm disallowing with pure functions because of the initial complexity of determining which version of a method to call).<br>
<br>
Can you clarify, Sven, with "static" and "class"?<br>

I gather you can't access Self in such methods.<br>

I did wonder about that, but wasn't sure how it would affect things where inheritance is concerned. I dare ask, do you have an example of a class method that you would consider pure?<br>

</div><div dir="auto">They don't have inheritance. If they have the modifier "static" they really are simply scoped functions or procedures. They can even be assigned to non-"of object" procedure variables. </div><div dir="auto"><br>
