This would be highly appreciated. My current solution is something like:

library(data.table);
result = rbindlist(lapply(list.files("*.csv"), fread));

Would love to have something like:

result = fread(list.files("*.csv"));

This, like #717, is something that seems to come up all the time.

Perhaps this could be a new (essentially wrapper) function freadl -- depends on how heavily we want to overload the file argument in fread.

Also related to #989.

I guess this is really just #2582 in disguise
