Bash Version: 3.1
Patch Level: 17
Release Status: release

Description:
        All these work fine:
        cat <~/.bash_history
        cat <(cat ~/.bash_history)
        while read f; do echo $f; done <~/.bash_history

    But, this fails:
       while read f; do echo $f; done <(cat ~/.bash_history)
       bash: syntax error near unexpected token `<(cat ~/.bash_history)

    This is important when the operations in the loop need to affect
    the current shell environment (as contrasted with a | pipe)

    Also duplicated error on linux bash 3.00.16(1)-release
        (i386-redhat-linux-gnu)

Repeat-By:
        See description.
