Different behavior for points inside of lists
To make a sheet covering a type of diagram that shows the increase of a graph (sort of the precursor to a derivative), I wanted to make a list of points which could slide vertically.
I knew the line "Point(PerpendicularLine((5,0),xAxis))" would give me a point which can be moved along the vertical line x=5.
I tried incorporating that into a sequence command, to produce 11 points, all of which would slide vertically along a line x = i, where i would span along the numbers from 0 to 10.
This does produce 11 points, but they can no longer be moved vertically.
I posted this as a bug report, but this might be a concious choice; I do wonder why the sequence command limits the movement.
