New description:

 tart zsh without rcs (this should start a new shell):

 {{{
 /usr/local/bin/zsh --no-rcs
 }}}

 try to enter the following in the new shell (it should hang):

 {{{
 echo $(date)
 }}}

 To me it seems like all command substitution using $() causes zsh to hang.
 Backticks seem to work though.

 (Copying report from
 https://github.com/Homebrew/discussions/discussions/141 ; this is about a
 problem with Homebrew, but I'm getting the same behavior with MacPorts0.
