Incorrect bracket kind allowed.

[python-processing-unit]

According to the specification section 4.4.2:

TNS indexing MUST use square brackets ([ and ]) with a comma-separated list of indices.

And the specification section 4.5.2:

MAP indexing MUST use angle brackets (< and >) with a comma-separated list of keys.

In the implementation, however, both square and angle brackets may be used for both TNS and MAP indexing.

Prefix REPL. Enter statements, blank line to run buffer.
