I think this has been mentioned before, but I don't think an issue was submitted (or at least, I couldn't find it).

Namely, readdlm() improperly handles Int64.
For example, given a text file consisting only of the line -9223355253176920979, readdlm gives the following incorrect result:

test=readdlm("test.txt",Int64)
1x1 Array{Int64,2}:
 -922335525317692160

I think we should use parseint and parsefloat there instead of float64_isvalid.
Shall update with a PR.

Used parseint, parsefloat and parse methods instead of float64_isvalid.
Used parse method when an abstract type is specified.

Used tryparse methods instead of float64_isvalid.
If return array is of Any type, try parsing as Int, Bool and Float64 before falling back to substring.
