From b1912e722428d4cbc803787e6598dcd79925d55e Mon Sep 17 00:00:00 2001 From: Zoltan Herczeg Date: Wed, 17 Jun 2020 15:35:02 +0200 Subject: [PATCH] Fix async function call parsing. (#3909) The "async" identifier processing is delayed until it is detected that it cannot be part of an arrow expression. The "async" identifier should be processed at this point, but it was not happened in this case.
