Don't really understand this part. It seems inconsistent if one calls, say,<br>
``` StringLiteralParser::<wbr>isValidUDSuffix(LangOpts(), "if") ```<br>

```true```<br></blockquote></div></div></div><div dir="auto"><br></div><div dir="auto"><span style="font-family:sans-serif">That is valid in the case of `operator ""if`, so `if` is a valid string literal suffix (as is any numeric literal suffix).</span><br></div><div dir="auto"><br></div><div dir="auto"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
