It regularly irks me needing to do things like:
FOO!= echo ${VAR} | tr ' ' : 
to get rid of the spaces between words in ${VAR} (eg for something
that can be passed as say $PATH to a command.)

I'd like to add a modifier that allows one to set or even supress
the character used to separate words in a variable expansion.
Even if this only worked in conjunction with the :@ modifier it would
be handy.

Before I burn precious cycles trying to come up with a name for this
modifier does anyone have suggestions or violent objections?

Thanks
