Description Dominique Hazael-Massieux 2012-12-21 14:31:46 UTC 
The current WebIDL grammar makes "-    Infinity" a valid float litteral, while "- 1.0" is not:
FloatLiteral	→	float
 | "-" "Infinity"
 | "Infinity"
 | "NaN"

I see little value in allowing space between the "-" and "Infinity", so I would suggest instead making the second production "-Infinity".
