The :help does hint at using BufWinEnter instead, which works for this case, but it seems suboptimal having these autocmd commands executed every time I display the buffer, when really I only need them executed the once, after buffer read/load.

But FileType autocmds get executed at every display of the buffer, not just when loading the file.

autocmd BufWinEnter * if &ft == 'perl' | exe input("BufWinEnter") | endif
autocmd FileType perl exe input("FileType")

These both wait for input when bringing forth via :b. I suppose I'd just have to set and check for a 'loaded' variable at the beginning of my commands.
