The C11 spec says that emoji should be allowed in identifiers 
(ISO publication N1570 page 504/522), so it's not just the cool

I'm not in favor of emoji in identifiers.

It's supported because λ is a letter in a language spoken by 
thirteen million people. I mean, would you want to have to name a 
variable "lumиnosиty" because someone got annoyed at people using 
"i" as a variable name?
