You "can" do it, even without eval(). But you definitely "shouldn't" do it. Suppose $1 contain 'INC' or 'ISA' or 'ARGV', and your program makes use of those. Your eval just zapped them. This kind of thing is why programs that "work fine" will suddenly, unexpectedly, break in mysterious ways months later.
