Don't use function, use "$name ()" instead.
What's wrong with function??
'function name' is a bash extension while 'name()' is POSIX. If you use
standard POSIX instead of bash extensions, then your approach will more
easily port to other POSIX shells.
It's not just a bash extension. Ksh and zsh also have the 'function'
keyword, probably other shells as well. I prefer it in ksh because it
makes locally declared variables really local, while with the name()
syntax they are shared with the environment. That's one reason why it
became a habit. The other is that 'function' is clear and
self-explaining, while 'name()' wrongly suggests that function
parameters should be surrounded by parentheses.
Apart from that, I can't see why I should care for POSIX when writing
bash-specific hacks.

Bernd
