In this PR we extract two new token
lt
(<
),gt
(>
) fromtt.relational
. The base parser does not care how they are modeled as long as thebinop
is correctly configured. However these tokens are heavily used in the flow/jsx/typescript plugin. Introducing new tokens will simplify how plugins match these tokens: so we can removeisRelational
andexpectRelational
method.This PR also splits
readToken_lt_gt
intoreadToken_lt
andreadToken_gt
.
