'eval' exit behaviour in posix mode
In current git, 'bash -o posix' no longer exits the shell on a syntax
error in the argument to the special builtin 'eval'. Bash 4.2-4.4 exit
as POSIX specifies.
$ bash -o posix -c 'eval "(" || echo woops'
bash: eval: regel 1: syntaxfout: onverwacht bestandseinde
woops
On the other hand, note that 'command eval' should *not* exit. Bash
4.2-4.4 exit on 'command eval "("' which is also a bug.
Thanks,

It's the specific case of an unexpected end of file. ksh93 doesn't exit, either, but it's probably the right thing to do, and the right thing for backwards compatibility.

Why not just use an environment variable such as LOADABLES_PATH (just like the way how PATH is used)? Is it too difficult to reach an agreement on this? As of 4.4.23, I still don't see such an environment variable. Anyway, any variable is better than no variable. -- Regards, Peng
