Description

Recently I found a bug when I add new feature in SqlParser. Which is :
If I define a KeyWord that has a long name. Like：
```protected val ：SERDEPROPERTIES = Keyword("SERDEPROPERTIES")```

Since the all case version is implement by recursive function, so when ```implicit asParser`` function is called and the stack memory is very small, it will leads to SO Exception.
