postcircumfix <>

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 postcircumfix 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.

What the interpreter said #

Raku++ parses this spelling. Asked to compile:

my %h = a => 1; sink(%h<a>)

…it got through the parser. On its own that establishes very little: it says nothing about whether the construct executes, let alone whether the result is right. Where the behaviour table below exists, that is the stronger evidence — those expressions were actually run.

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.
