Review Comment:
This shouldn't be necessary as Long is sufficient for Java. The reason this
is needed for TypeScript is because numbers are stored as floats so there is a
`Number.MAX_SAFE_INTEGER` which will likely get exceeded in this
multiplication. That makes BigInt safer for the TypeScript version.

> Key: TINKERPOP-3153
> URL: https://issues.apache.org/jira/browse/TINKERPOP-3153
> Project: TinkerPop
> Issue Type: Improvement
> Affects Versions: 4.0.0
> Reporter: Ken Hu
> Priority: Major
>
> Types to add to the grammar in 4.0:
> * Char
> ** Unfortunately '' is already used for strings to match Groovy. Will need
> to look into something nice for this.
> * Duration
> ** Should check to see if Duration can be used for date functions as well
> ** Duration(Long)
> * CompositePdt
> ** Pdt("name", [ : ] )
> * PrimitivePdt
> ** Pdt("name", "value")
> * Tree
> * Graph
> * Binary (ByteBuffer) - moved from 3.8.0
> ** {{Binary( '/9j/4AAQSkZJRgABAQEAAAAAAAD/==')}}
