###################################################################################
If i enter a command line like below then '>' prompt appears for the
input of here document.
bash$ { cat <<\@ > foo ;} 2> /dev/null
> 111
> 222 # '>' prompt
> @
but if i use alias then '>' prompt does not appear and default bash
prompt appears
bash$ alias myalias='{ cat <<\@ > foo ;} 2> /dev/null'
bash$ myalias
bash$ 111
bash$ 222 # bash$ prompt
bash$ @
this only occurs in brace
bash$ alias myalias='( cat <<\@ > foo ) 2> /dev/null'
bash$ myalias
> 111
> 222 # '>' prompt
> @
