This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

If you have a constant expression like 1 + 2 in your code you can evaluate it at compile time once and avoid computing it at runtime. You can do that with control flow and much more complex language constructs in C++. If you want to know more about that look into C++ template meta programming, constexpr, and constval.

Or don't look into those things if you wish to remain sane

Templates are cool as fuck tho... For like 5 minutes until you go insane

I get that the designers wanted to have compile time static replacement but this was not the way to do it.

yeah, zig and rust have the same concepts but much better thought and structed

It's easy to build a well-designed language when you don't have to work around the mistakes of the past that were too difficult to solve then and too deeply entrenched to change now.

yes, thats why I dont bother finnishing projects

To be fair, I never fully understood why programming projects have to be native Finlanders, in the end.
