The rego_version field is not getting respected in the REPL

[tsandall]

It seems the REPL has trouble with the rego_version field:

torin:~/scratch/rego-v1-exp$ ls -al
total 8
drwxr-xr-x   3 torin  staff    96 Jul 15 15:07 .
drwxr-xr-x@ 51 torin  staff  1632 Jul 15 14:22 ..
-rw-r--r--   1 torin  staff    33 Jul 15 15:05 x.rego

x.rego is v1 compatible.

torin:~/scratch/rego-v1-exp$ cat x.rego
package foo

p := 7 if { 3 < 4 }

Building a bundle with --v1-compatible and then running the REPL with the bundle produces an error:

torin:~/scratch/rego-v1-exp$ opa build --v1-compatible x.rego
torin:~/scratch/rego-v1-exp$ opa run -b bundle.tar.gz

2 errors occurred:
bundle.tar.gz/x.rego:3: rego_parse_error: var cannot be used for rule name
bundle.tar.gz/x.rego:3: rego_parse_error: rule name conflicts with built-in function

Note opa run -s -b ... and opa eval work fine.

EDIT:

You can run workaround this REPL bug by specifying opa run --v1-compatible ... when starting the REPL. This works as long as all bundles you are loading are v1 compatible.
