ini bukan kombinasi itu saja...
dari bash(1) :
RESERVED WORDS
Reserved words are words that have a special meaning to the shell. The
following words are recognized as reserved when unquoted and either the
first word of a simple command (see SHELL GRAMMAR below) or the third word
of a case or for command:
! case do done elif else esac fi for function if in select then until while { } time
[[ ]]
---
Compound Commands
....
{ list; }
list is simply executed in the current shell environment. list must be
terminated with a newline or semicolon. This is known as a group
command....
jadi kalo anda suatu waktu -atau- sudah terbiasa dengan 'function' di bash,
benda itu akan berdampak 'usefull' atau 'useless' tergantung dari habbit
programmingnya dimana.
