Hi all,  
I am using IRTools and would like to change my IR in such a way that the whole **body is wrapped** in a simple

```julia
try
  ...
catch e
  return nothing
end

```

I couldn’t find help in the documentation [Home · IRTools](https://juliahub.com/docs/IRTools/oFGpw/0.4.0/#Manipulating-IR-1) and hence hope that someone might be able to help.  
Thanks a lot
