" This checker runs 'perl -c' against your file, which in turn executes
" any BEGIN, UNITCHECK, and CHECK blocks, and any use statements in
" your file. This is probably fine if you wrote the file yourself,
" but it can be a problem if you're trying to check third party files.
" If you are 100% willing to let Vim run the code in your file, set
" g:syntastic_enable_perl_checker to 1 in your vimrc to enable this
" checker:
"
" let g:syntastic_enable_perl_checker = 1
