Since /usr/bin/which is a /bin/bash script, it shares the disadvantage
of (H).  More so, because now you're running *two* shells whereas a 
#!/bin/bash script would only need one :)

The irony is that the only reason to use which is to accomodate speed
freaks who want to be able to use non-bash shells.  Now they get hit
by the bash startup time anyway.  And those same speed freaks are
likely to be using ash, which has both "type" and "command -v". 

I once again recommend a deathmatch between ash and zsh fans.  Let
the best shell win.
