I hate the dangling dots.

jk:12> a = [20;3]
a =

  20
   3

jk:13> 1/a
ans =

  0.0488998  0.0073350

jk:14> 1./a
ans =

  0.050000
  0.333333

jk:15> 1. / a
ans =

  0.0488998  0.0073350

So now the space changes things.

The dot will adhere to the "/" rather than the "1".  The problem is
you have to try it to see which way it goes.

Also annoying is matlab using ' for both complex-conjugate-transpose
and string quote.  In octave we can use " for strings but then it's
not compatible.
