The docs mention an "abuse of notation" czse,
but in v2.17.0 that doesn't work as mentioned:

? my(v=vecsort([3,0,2; 1,0,2])); printp(v); vecsearch(v, [3,1]~)

[0 2 3]

[0 2 1]

  ***   at top-level: ...=vecsort([3,0,2;1,0,2]));vecsearch(v,[3,1]~)
  *** ^-------------------
  *** vecsearch: incorrect type in vecsearch (t_MAT).
