Lumo does not have source maps in the REPL

[arichiardi]

While peeking at planck I tried to require a simple file:

(ns ping-pong.core)

(def a 3

I also checked:

$ ls .lumo_cache/ping_pong_SLASH_core.*
.lumo_cache/ping_pong_SLASH_core.cache.json  .lumo_cache/ping_pong_SLASH_core.js

So it seems that we don't have source maps enabled in the REPL.

Related to #35

[arichiardi]

Actually the error message is accurate because it is a reader error.

I didn't expect to see things like evalmachine.<anonymous>:163:47 and I am sure there is a simple answer to this.

[arichiardi]

Some work for improving this is in #349

[anmonteiro]

This is a duplicate of #35, why did you open another issue?

[arichiardi]

At the time they looked different. We can close this one.
