`columnnames` sometimes returns property names

[ParadaCarleton]

using CSV
data = CSV.load("filepath.csv")
Tables.columnnames(data)
# returns (:filename, :delim, :keywords)--property names--instead of column names

Indeed type returned by CSV.load seems to need to override the default return-value (or define getproperty differently)

[ParadaCarleton]

Yep. Besides that, is the default (automatically return properties) a good default, or should it error for types that don't have a defined method?

The default has always been to return propertynames.
