Disable most shell expansion to function or script

["Sam B." <me@xxxxxx>]

Hello,

I'm looking for a way to disable most shell expansion for the arguments 
to a script or function and treat everything up to a newline char as 
verbatim text, i.e. as if quoted.

For example, given a function/script "todo", I'd like

    todo Text inc. $var, *glob?, events!, <redirs, >(sub) & more

to behave more like it was quoted:

    todo 'Text inc. $var, *glob?, events!, <redirs, >(sub) & more'

I know of noglob to disable glob chars, and can have a look at histchars 
to see if events can be disabled. But I'm not sure if any of the other 
expansion can possibly disabled.

Mostly I'm interested joting down some plain text which could include 
'?!&' and have "todo" receive it all without the shell having done some 
magic beforehand.

Any ideas?
