I think that this must be an inconsistency in Espruino

a = "1"
="1"
a++
="1"
a++
="11"
a++
="111"
a = "s"
="s"
a++
="s"
a++
="s1"
a++
="s11"
a++
="s111"

I would have expected (and comfirmed using javascript console in chrome) that if the string were a number it would return 1 , 2, 3 otherwise it would return NaN rather than concatenate 1 on the end.

Is this a bug?
