[kulowf]

On Julia 1.11.0, 1.10.4, 1.9.0, Win10; Julia 1.8.3 on Ubuntu

while true   
    function f()
        @warn "active function"
    end

    f()
	
    break    
    function f()
        @warn "inactive function"  
    end
end

output of this:

Warning: inactive function

Is this a bug or a feature?
