Description

With paren:

def a(arg1, arg2)
  p arg1, arg2
end

a(<<~EOS.chomp, 1)
  123123
EOS

Without paren:

def a(arg1, arg2)
  p arg1, arg2
end

a <<~EOS.chomp, 1
  123123
EOS

For anyone who ends up investigating this, it is related to the grammar file. We do not push semantic highlighting tokens for heredocs or parenthesis as they are not ambiguous tokens.

Is there any update here? this isn't only a problem with parens. Ruby syntax doesn't recognize squiggly heredoc blocks as a string either:
