This is not ironical; websockets are an interface made specially for the browser. 
Websockets are useless somewhere else, where everyone uses TCP/IP long before the browser existed. 
So, since JS is the language for the browser, naturally there will be lots of websocket clients.

And: I repeat, I am not advocating against people using Delphi mode.
People that care about Delphi syntax and compatibility should use 
Delphi mode, period.

Mode objfpc is meant to implement new features in a more pascal like fashion - in the opinion of the FPC devs.
If you don't agree: no problem. Use mode delphi.

I am not stopping anyone from using generics. I am just not convinced by your arguments.
The code you posted - to me - only shows that your design is wrong to begin with.
(see the remark by Graeme).

Generics, to me, are just there to circumvent or assuage the strict typing of pascal.
This is very un-pascalish. Javascript does not need generics because it has no strict 
typing to begin with.

JS has no attributes either, in fact, it has none of the features you claim will help you.
Yet you will move to Node.js, and so to JS. Why ? 
Simple: there is a bigger community, and more ready-to-use code floating on internet. 
The language itself has absolutely nothing to do with it.
