I think of head() as a standard helper for "glancing" at objects, so I'm
sometimes surprised that head() produces massive output:
M = matrix(nrow = 10L, ncol = 100000L)
print(head(M)) # <- beware, could be a huge print
I assume there are lots of backwards-compatibility issues as well as valid
use cases for this behavior, so I guess defaulting to M[1:6, 1:6] is out of
