Re: How to test if a file is gzipped or not

[sectokia]

IO::Uncompress::AnyInflate will gunzip data, and has a Transparent option. The option is useful as you can select if you want non-gzipped data to just pass through and be returned as if it was the uncompressed result, or if you want it to throw an error.

TIL IO::Uncompress::AnyInflate exists.

I don't know if it's important for Special_K, but I read under "Transparent":

In addition, if the input file/buffer does contain compressed data and there is non-compressed data immediately following it, setting this option will make this module treat the whole file/buffer as a single data stream.

This might pose a security risk, if one isn't aware of it.
