You can't grep for it, but you can grep `unsafe`

[mattdw]

`ptr`, `addr` and `cast` are the only ways to introduce unsafety, as I understand it. You have to run three greps, but you can definitely grep.

[cb321]

`grep -w 'pointer|ptr|addr|cast'` would do it in one.. (One can surely do a shell alias called `find-unsafe`..).

Finding unsafe constructs in Nim code is not that hard, at least at the same level of accuracy as `grep unsafe *.rs` (e.g. inside comments & strings, etc.).

To evaluate the power of this general line of argument, consider -- if Nim shipped with a `find-unsafe` source-level search utility, how much would this change your mind?
