Debugger appears to step into an if statement even if the condition is false.

[mkitti]

The debugger appears to step into an if statement if no other statements follow it. Below the debugger goes from line 2 then proceeds to line 4 within the if statement before returning.

julia> using Debugger

julia> struct Circle end

julia> function test_circle(circle::Circle)
           if typeof(circle) == "Circle"
               println("Thou shall not pass!")
               println("Hello world!")
           end
       end

If I add a return statement, then the stepping appears correct. It advances from line 2 to line 6.

julia> function test_circle(circle::Circle)
           if typeof(circle) == "Circle"
               println("Thou shall not pass!")
               println("Hello world!")
           end
           return nothing
       end
