Unless you need to run programs with arguments with spaces in their name.
Not that long ago, I needed to write a script that would grab the last command in a shell file that had a list of commands, add an argument or two to it, and run it. Which proceeded to barf because the command had quotes, for some of the arguments had necessary spaces in them, and I couldn't figure out the way to get the necessary string in a way that bash could properly execute the command. My eventual solution was to just use python's shlex module to parse the line and output an executable command (and remark that I should have just started the script in Python in the first place)...
