[dev] [question] Does bash suck?

[Marc Collin]

Hi.
Recently a user from suckless told me that bash sucks, but before I
could ask why he went offline.
I tried looking at suckless.org page about software that sucks, but
couldn't find anything about bash.
I can imagine why it sucks  - no portability! #/bin/sh should be
enough for everyone. Is that it or is something else to the matter?
Maybe an entry to suckless.org suck page could be good to clarify
things and also warn new users.
Best wishes.
