ISKEYWORD ignores words in hints such as nolock, hash

Comece executando o script do PowerShell fornecido com TSql150Parser e inspecione a saída de ScriptTokenStream para nolock e hash, concentrando-se em seus tipos de token e nos resultados de IsKeyword(). Rastreie como TSql150Parser classifica essas palavras de hint e verifique se a classificação corrigida é refletida no fluxo de tokens sem erros de parsing.

• SqlPackage or DacFx Version:
• .NET Framework (Windows-only) or .NET Core: .NET Framework
• Environment (local platform and source/target platforms):
  Parser for 2019, Windows
  Steps to Reproduce:

1. Powershell script as below - does not recognize nolock , returns no for iskeyword.
   $ScriptData = @"
   --Testing tokens
   begin tran
   SELECT * FROM mytable (nolock);
   commit tran
   "@

Add-Type -Path "C:\ugpresentation\ScriptDom\Microsoft.SqlServer.TransactSql.ScriptDom.dll"
Write-Host "Attempting to parse..."
try {
$parser = New-Object Microsoft.SqlServer.TransactSql.ScriptDom.TSql150Parser($true)
#object to handle parsing errors if any
$parseErrors = New-Object System.Collections.Generic.List[Microsoft.SqlServer.TransactSql.ScriptDom.ParseError]
#object that handles strings script to parse
$stringReader = New-Object System.IO.StringReader($ScriptData)

#parser creates parsed objects from strings 
$parsedObjects = $parser.Parse($stringReader, [ref]$parseErrors)
$ctr = 0

 foreach ($token in $parsedobjects.ScriptTokenStream)
{
    write-host "Text: " $token.text -ForegroundColor Cyan
    write-host "Type: " $token.tokentype -ForegroundColor green
    write-host "Location: Line" $parsedobjects.ScriptTokenStream[$ctr].Line "Column " $parsedobjects.ScriptTokenStream[$ctr].column  -ForegroundColor yellow
    write-host "Is this a Reserved Word? " $token.IsKeyword()-ForegroundColor white
    $ctr++
} #token
if($parseErrors.Count -gt 0) {
    throw "$($parseErrors.Count) parsing error(s): $(($parseErrors | ConvertTo-Json))"
}
Write-Host "Complete!" -ForegroundColor Green

}
catch {
throw
}

Did this occur in prior versions? If not - which version(s) did it work in?
