The rules for .= have not been written yet. Everything below is extracted rather than authored: the official documentation supplies the classification, and the interpreters were asked directly about the rest.

What is established #

Classification #

.= is parsed as a methodop at the method call precedence level, left-associative.

That is level 2 of 27 on the ladder, counting from the tightest. Operators sharing a level bind equally; grouping among them is decided by associativity alone.

Shares its precedence level with #

[[ ]](/spec/rules/operators/postcircumfix-brackets/), { }, <>, < >, « », ., .&, .^, .?, ."", .+, .*, ». / methodop >>., .postfix / .postcircumfix, .:<prefix operator>, .::.

These all bind equally tightly, so an expression mixing them groups by associativity alone.

Covered upstream #

The official documentation has a section for this construct: docs.raku.org. Until the rules here are written, that is the better reference.
