`@run sum(5+1)`| run debugger, stop at error/breakpoints
`@enter sum(5+1)` | enter debugger, dont start code yet
`@show variable` | prints: variable = variablecontent
`@debug variable` | prints only to debugger, very convient in combination with `>ENV["JULIA_DEBUG"] = ToBeDebuggedModule` (could be `Main` as well)
