closes #6113
Passing
header=True|False
toread_csv
(and brethren),read_excel
, andread_html
will now raise aTypeError
, rather than being coerced to an int.I had thought about converting
False
toNone
but thought that could break someone's code in a very subtle way if they were somehow depending on the old behavior. But happy to change that if it seems better.If you want to push this in for 0.17 I can add a doc-note or this could easily wait.
