Pike v7.6 release 117 running Hilfe v3.5 (Incremental Pike Frontend)

Crypto.DES3()->set_encrypt_key("\x01\x23\x45\x67\x89\xab\xcd\xef"+"\x01"*8);

DES3_INFO: Key is weak. src/post_modules/Nettle/cipher.cmod:785: Nettle.DES3_State()->set_encrypt_key("\1#Eg\211«Íï\1\1\1\1\1\1\1\1") HilfeInput:1: HilfeInput()->___HilfeWrapper()

Well, never you mind! I need to use this particular key for testing, and don't care that it's weak (it's just a test key anyway).

The autodoc says

/*! @decl CipherState set_encrypt_key(string key, void|int force)

but that doesn't seem to work either:

Crypto.DES3()->set_encrypt_key("\x01\x23\x45\x67\x89\xab\xcd\xef"+"\x01"*8, 1);

Compiler Error: 1:Too many arguments to set_encrypt_key. Compiler Error: 1:Expected: function(string : { this_program = object(implements 65740) }) Compiler Error: 1:Got : function(string, int(1..1) : void | mixed)

What gives?
