in any other situation difference will be even less than 10% :)

IJ> Writing "image.at(i) = ..." gives me a parse error. Why?

y=a[x]  # used method "[]", equal to y=a.[](x)
a[x]=y  # used method "[]=", equal to a.[]=(x,y)
y=a.at(x) #used method "at"
a.at=y    #used method "at=", equal to a.at=(y)
a.at(x)=y #is not ruby syntax
