Hiya!
There are a couple of spelling errors:

• delimeters -> delimiters

➜  grep -irnw delimeters         
README:612:    delimiters are both on the first line, and the closing delimeters both
lib/Data/Dumper/Compact.pm:1035:delimiters are both on the first line, and the closing delimeters both on

• intead -> instead

➜  grep -irnw intead              
lib/JSON/Dumper/Compact.pm:70:arrayrefs and hashrefs intead into JSON.

• throught -> through

➜  grep -irnw throught  
lib/Devel/DDCWarn.pm:217:C<$ddc> used by this code and change all output throught the process.
