Well..... the problem might not be as bad as the shell's handling of 'exec'.
I think it just has to do with alias interpretation.

The thing with aliases is that the shell will only interpret an alias like
alias ls 'ls -F' if it's the first thing in the command line. (or the first
thing after a "|" , or enclosed in a ``, or the like something.) So even after 
alias foo '| more', and typed w foo, it would certainly not do w | more.

It WOULD be nice if csh had a "global" alias option, but then there's the 
chicken and egg problem of resourcing your global alias file after you've
already done so. 

i.e 

alias foo '| more' 

is a global alias. The next time you sourced this file it might be interpreted
as 

alias '| more' '|more' which would make no sense.

I guess this could be turned off during alias addition. Any other ideas?
