Rename system chaining to system welding

[alice-i-cecile]

System chaining sounds very innocuous and helpful: new users will often want to use it for either general purpose system communication or system ordering.

Both of these are very wrong. Renaming it to system welding better captures the irreversible one-to-one nature of the operation.

Docs have also been cleaned up slightly to steer users in the correct direction.

I quite dislike weld, but I'm not sure I have anything better to offer. Maybe and_then to at least follow something from rust std lib. fuse could be closer to the weld idea.

[alice-i-cecile]

That's perfectly fair: weld was Ratys's suggestion on Discord when I asked.

pipe is probably my personal favorite, but I'm not sure if the usage here is close enough to the standard use. fuse feels a bit off to me (as does weld) due to the lack of implied directionality to it.

What about join or combine or merge? They sound like irreversible words and they are not as obscure as weld.

Other options:

I think pipe has a connotation similar to chain that will make users want to use it for system ordering.

I think pipe has a connotation similar to chain that will make users want to use it for system ordering.

I think I agree with this.

I'd like to avoid join, combine and merge due to overloading if possible.

The thesaurus links were helpful though: splice captures what we want: a directed, irreversible, one-to-one joining of two systems.

I'm personally not a big fan of splice tbh, since it isn't a very commonly used word, making the API trickier for non-native speakers. I think we should stick to more commonly used words. I'd personally be happier with fuse or weld.

[andresovela]

I agree, as a non-native speaker, I'd have to look the word up in the dictionary to double-check the meaning. fuse and weld are more common IMO, but I'd be more inclined to use fuse than weld.

Theres also a lot of overlap with map semantics. Basically identical if you consider system arguments to fill the same role as captured variables in closures.

[alice-i-cecile]

Closing this out, without consensus and a much better name it's not worth the churn right now.
