The commit that broke this is:

The provided solution of detecting a call in the lexer is incorrect as there
might be an expression that starts with a bracket.

Test code to add in lang.vbs:

Sub TestWithBracketsAtStartFirstArg(a)
    Call ok(a=2, "a = " & a & " (expected 2)")
End Sub
TestWithBracketsAtStartFirstArg (1) + 1
