importing pandas will cause a file called "parser.py" in the CWD to be imported
In python3 when I import pandas from the interactive session, if there is a file called `parser.py` in the current working directory the file is imported as part of the process. I am running Mac OS 10.10.5 with python 3.4.3 and using pandas 0.16.2 installed with homebrew.

pandas should not be importing random files when it is imported. The only reason I noticed this is that the file had a syntax error. If my `parser.py` had been doing file operations on import this could have causes serious harm.

My full version of pandas is

To see this I wrote a small file called `parser.py` and put it in \ ran python (with -v) then imported pandas. Below is a condesed part of the output.

   Reids-MBP:/ Reid$ echo "Print('You are in my parser.py')" > parser.py
   Reids-MBP:/ Reid$ echo "Fail here" >> parser.py
   Reids-MBP:/ Reid$ python3 -v
