          Hardware: Unspecified

https://github.com/WebKit/webkit/blob/master/Source/JavaScriptCore/parser/Lexer.cpp#L2104

Was browsing the source to see how numbers were parsed for potential complexity in supporting proposal https://github.com/tc39/proposal-numeric-separator .

I found that only 'x', 'b', and 'o' is supported for numbers, although the standard says that capital or lower case letters should be allowed.
https://www.ecma-international.org/ecma-262/6.0/#sec-literals-numeric-literals
(ES6) I see that ES5 did not support 'o' or 'b' either.
