Um, no, eval prevents dieing, Safe prevents ops you don't allow (in theory) like exit, system, etc

[thomas895]

Safe can -- if (ab)used correctly -- prevent your program from dieing as well.

[ikegami]

Safe can prevent die from being called, but not dying in general, or even due to "bad" derefs.

If you wanted to change the behaviour of `->`, especially in a lexical scope, you could use an opcode checker. The autovivification pragma is an example of such.
