@AlekseyTs Do you find this change an improvement?

[AlekseyTs]

I like the idea of renaming. There is one suggestion, "CanGet" should probably be "CanPeek".
It feels like the change itself introduces too much churn. I would prefer it to be straight rename, no reformatting of the code. For example, I do not find a change like the following (conversion to a single-line If) an improvement:

•                If CanGetCharAtOffset(1) AndAlso BeginsBaseLiteral(PeekAheadChar(1)) Then
  

•                    Return ScanNumericLiteral(precedingTrivia)
  

•                End If
  

•                If CanGet(1) AndAlso BeginsBaseLiteral(Peek(1)) Then Return ScanNumericLiteral(precedingTrivia)
  

Reformatting of conditions from multiple line to a single line fall into the same category, etc.

@AdamSpeight2008 Can you please update your pull request to address the comments from @AlekseyTs ?

Could you please keep the newline after the OrElse in the condition.
Now I need to scroll right the diff on GitHub to see the end of the proposed line.
