`mlr check -n 1000` would be nice (and easy to code up). Meanwhile you can do ``` $ wc -l medium.dat 10000 medium.dat $ mlr put 'NR % 1000 ==...

Hi @jgarthur !! Thanks for submitting this! :) I think the `test.csv` example may be due in part to a "baseline RSS" rather than a leak issue ... there are...

if there are no embedded spaces in any column values, use `--ipprint`. if there are though ... there's no fixed-width ingestor.

@Poshi I stand corrected. Miller 5 -> 6 (C -> Go) didn't change behavior here. What I was recalling above as being "absolutely" true was the behavior for `stats1` --...

Note `mlr step` behaves like `mlr stats1`: ``` $ mlr --c2p --from input.csv step -a rsum -f x,y,z x y z x_rsum y_rsum z_rsum 3 6 - 3 6 -...

Thanks @Poshi ! You're right, you found another inconsistency. To be clear though -- I very much think this change needs to be made; I'm in agreement. Thanks for helping...
