Changing the global “path” from within a function

Vote count:

My zshenv file has a bunch of lines like

if [[ -d "$HOME/bin" ]]; then
    path=($HOME/bin $path)
fi

I thought I’d try to factor this pattern out into a function. I replaced it with

function prepend_to_path_if_exists() {
    if [[ -d $1 ]]; then
        path=($1 $path)
    fi
}
prepend_to_path_if_exists("$HOME/bin")

but this gives the error

/Users/bdesham/.zshenv:8: missing end of string

where line 8 is the one where I’m calling prepend_to_path_if_exists. What exactly is causing this error, and how can I make this function work? I’m using zsh 5.0.5 on OS X 10.10.1.
