This is really confusing. In the REPL one can evaluate a stream to get useful info on what the object is:
julia> f IOStream(<file test.txt>) But in a script, just "f" would not work, so for debugging I try to print it to stdout: julia> print(f) [empty] julia> println(f) ERROR: attempt to write to a read-only IOStream in write at iostream.jl:208 in println at string.jl:5 julia> print(repr(f)) IOStream(<file test.txt>) I thought that "write" was the method to write to a file. Why is there this strange re-use of "println"? I suggest a "writeln" if it is just to append a newline to a file. Why does "print" not use the representation of the object? Am I supposed to use "repr" every time, or am I just debugging the wrong way?
