Spec for a leading infix operator needs clarification

[eed3si9n]

Compiler version

3.2.2.

Steps

• https://docs.scala-lang.org/scala3/reference/syntax.html
• https://docs.scala-lang.org/scala3/reference/changed-features/operators.html

Problems

1. Scala 3 Syntax Summary page does not mention about he leading infix operator.
2. Rules for Operators page uses terms like symbolic operator/identifier/names, but they are undefined.

Expectation

1. Scala 3 Syntax Summary should include a summary of leading infix operator rules.
2. Scala 3 Syntax Summary should define symbolic operator/identifier/names.
3. Rules for Operators page should also define symbolic operator/identifier/names.

Notes

Based on the implementation of isOperator https://github.com/lampepfl/dotty/blob/3.3.0/compiler/src/dotty/tools/dotc/parsing/Scanners.scala#L87-L89, I am assuming that symbolic operator/identifier/names is defined to be:

1. A backticked identifier
2. An identifier whose last character is an op character

I always intended to check the feature in -Xsource:3, as the implementations necessarily diverged.
