I wanted to better understand the current position of @heather.miller and the Scala Style Guide team about Unicode arrows, meaning:
As you know the Scala compiler accepts the above Unicode arrows, treating them in the same exact way of their standard two-ascii-chars version.
In particular my question if it is acceptable to use them publicly in mainstream Scala projects.
Of course I am totally in favour, they seem to me to increase the readability of the code.
The only reference I found about this topic is https://issues.scala-lang.org/browse/SI-988. But is 10 years old, and by now the Unicode support is if possible even larger.
If you think this is something that can be promoted, one possibility I have in mind is also to write a scalafmt optional rewrite rule.
I look forward to your comments.
