When looking at a code that uses domain literals in vim with syntax highlighting, all curly braces after the domain literal are marked as errors (highlighted in red).
For example, in the code:
proc f(d: domain) { }
proc main {
f({1..5});
for i in 1..5 {
}
}
Every curly brace including and after {1..5} are highlighted in red.

It doesn't happen very often, so I have to say it loud and proud:
Fixed by #12563.
