Re: Saving canvas as ROOT macro

Vassili,

You are creating the problem yourself by using object names containing blank characters.
In ROOT in several places the pointer names are automatically derived from the object names (SavePrimitive, but also when writing the object to a file). We do not want to replace systematically the blank characters by other special characters like the obvious "_" because this would imply creating
a temporary string in the general case and deleting it for every GetName operation and this would penalize the majority of users.
