Outdated egg!

This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.

If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

• if the VALUE is a blob, it will be packed as bin.
• if the VALUE is a char, it will be packed as a uint.
• if the VALUE is a list, it will be packed as an array.
• if the VALUE is a extension (see below), it will be packed as an ext
