Fix compile error

[ngeiswei]

I was getting the compile error

error[E0425]: cannot find value `eo2` in this scope
    --> experiments/expr/bytestring/src/main.rs:1957:80
     |
1957 | ... eo1, eo2]) {
     |          ^^^ help: a local variable with a similar name exists: `eo0`

so I fixed the best way that I can.

Needless to say, double check cause I have almost no idea what I am doing.

Facing this issue while compiling the mork_server package (from server branch).
Not sure if we do what Nil is doing or just delete eo2 from that list.

Compile from the server directory, not the root

Compile from the server directory, not the root

That works, thanks!
