autoload syntax

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

All,

Sorry for such an elementary question but I'm fishing around looking for 
sample .zshrc files to play with and I keep coming across several 
syntaxes for this sort of thing:

autoload -U compinit
compinit

or:

autoload -U compinit compinit

or:

autoload -U compinit ; compinit


Which of these is the most kosher?

I get the feeling I could root around in zsh for the next decade and 
still only have scratched the surface of what you can do with it!
