We don't brace completion on '<'

[fionafung]

In writing generics, I notice that we don't brace complete on '<'. I got used to our great support of all the other types of braces :)

This is a very weird case because < is actually a binary operator on its own; however, if we're sure we want this, it can be implemented by only completing if the previous character is part of an identifier (note, I said "part of an identifier", not "not whitespace"; for instance, << cannot result in <<>).

Looking into a safe way to do this. We could do a regex to look for an id token on left, but I don't think that's sufficient because I can say a<b and that can mean a less than b or type a<b... finished by a closing >.

[steveluc]

Now with HTML escapes: I can say a<b and mean either a less than expression or the prefix of a<b>

[DanielRosenwasser]

That's true, but that depends mostly on whether or not you tend to have whitespace around your operators. Again, I can see this being a point of contention for users.

Any final thoughts on this? Otherwise I think this is too ambiguous. There's a few heuristics we could try, but not sure if the cost justifies the value.
