I just saw in the style guide the rules for casing.

I didn't expect this to exist because it doesn't seem to be obeyed ^^. For 
instance WalkUpFrom* starts with Upper-case.

I'll follow-up with a patch fixing any style problems of this nature.

I agree.
However there are some things that change between semantic nodes that produce 
an `IdExpression`.

* We may or not have a link from `IdExpression` to the AST.
* The `SourceRange` for the `UnqualifiedId` is obtained in an ad-hoc manner.

Taking into these variables we could write a function `buildIdExpression`

1. `IdExpression* buildIdExpression(Expr* E, SourceRange UnqualifiedIdLoc, bool 
shouldLinkToAST);`
2. `IdExpression* buildIdExpression(SourceRange QualifierLoc, SourceRange 
TemplateKwLoc, SourceRange UnqualifiedIdLoc, ASTPtr link);`

The first option takes into account only the differences that we perceived 
until now.
The second option provides a more general approach.
