VimScript tips needed

I want to write a fairly simple VimScript function, but I'm having trouble getting started.

I'm hoping a kind soul can give me some tips or point me to a similar script to use as an example.

Here's what I want to do:

- move to the beginning of the current line (:normal '^' seems to work)

- find the first occurrence of => on the line

- determine whether that is followed by optional whitespace and {

There's more, but maybe if I can get this far, I can figure out the rest.
