Reserved keywords as variable names with escaping

var \u{63}ase = 123;

outputs

var case = 123;

which is invalid.

https://jlongster.github.io/prettier/#{"content"%3A"var \\u{63}ase %3D 123%3B"%2C"options"%3A{"printWidth"%3A80%2C"tabWidth"%3A2%2C"singleQuote"%3Afalse%2C"trailingComma"%3Afalse%2C"bracketSpacing"%3Atrue}}

I had no idea you could even write that! This happens for all the reserved words (switch, let, var…). The proper fix is likely to escape the first character for all of them.

Yeah I believe it just means https://github.com/babel/babylon/issues/206 would need to be fixed

OMG you can write that??
