[ruby-core:120476] [Ruby master Bug#21003] unexpected warning about ignored block
Issue #21003 has been reported by decuplet (Nikita Shilnikov). ---------------------------------------- Bug #21003: unexpected warning about ignored block https://bugs.ruby-lang.org/issues/21003 * Author: decuplet (Nikita Shilnikov) * Status: Open * ruby -v: ruby 3.4.1 (2024-12-25 revision 48d4efcb85) +PRISM [arm64-darwin24] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- I stumbled upon this during the upgrade to 3.4. Here's the minimal repro: ```ruby $VERBOSE = true def foo(*, &block) = block def bar(buz, ...) = foo(buz, ...) bar(:test) {} ``` It gives ``` ruby reproduce.rb reproduce.rb:6: warning: the block passed to 'Object#bar' defined at reproduce.rb:4 may be ignored ``` where I believe it shouldn't. No warning reported if I change `def bar(buz, ...)` to `def bar(...)`. -- https://bugs.ruby-lang.org/
