`IncompleteConditionalStatementError` not exported from `index.ts`

[Simon Mumenthaler]

I wanted to properly handle the errors and noticed the IncompleteConditionalStatementError is not exported from the index.ts.
After looking into the source code it seems a bit odd not exporting this one. Is there a particular reason for it?

(version 4.11.1)
