I find the preparser perilous. It does some great things, such as the "F.<a> =" syntax. But every addition seems to come with a high cost. The *.sage/*.py dichotomy is confusing for new folks who want to write scripts immediately. And then there is the whole Integer() quagmire.
On the flip side, I have never bristled at Sage syntax for matrices. And I hardly ever type in a matrix anyway, except when doing dumb little tests. If I need a small "classroom example" I use the various versions of the random_matrix() constructor repeatedly until I get a matrix with the desired properties *and* the desired aesthetics. What I would really like to have is a routine that prints a matrix in a (column-aligned) form that is acceptable input (continuation markers, etc) so it can be cut/paste into doctests, worksheets, and examples. (Yes, I know Mathematica's InputForm[].) Not a hard thing to build, just have not reached that far down my list yet.
