k+len(p)

k+len(p)(pronounced kay-len) is a variant of _ created by User:Yayimhere, simply to be closer to turing complete. it features the whole _ command set but one command, but the esolang is also with three extra commands

Command set

k+len(p) uses the following command set:

Command	Effect
%	Delete a character from the end of the source code.
^	Skip the next command if the last character in the source code is ^.
\	Append the next character to the end of the source code and skip it.
+	Reverse the source-code and then append the whole program to the end of the program, without adding the first character of the source code. Note that the code pointer keeps its index.
Anything else	Redefine that character as the code that follows it, and append it to the end of the program. Now that character will be ran as a command doing that code(in place)

Computational class

I dont know, but I would guess turing complete. However remembering the proof of FSA'ness, we see something interesting. If we label the length from the end of the program k, we see that whenever + specifically is ran we see something interesting happens to k's value, specifically, k is set to k+len(p)-1 where p is the program string. As you see, differently form the other commands, it increases the program length. Most interesting is that now, any value of k is possible using + \ combinations.
