I don't hear Lispers or C programmers complaining. Yes, you can shoot
yourself in the foot with macro trickery, but macros can greatly enhance
code readability and remove the need for code generators. That's why
they are used extensively in Linux kernel code and GOOPS (Guile's object
system), for example.

Perl does that by forcing you to prefix you variables with $ et al. The
analogy would be:
for $for in @in:
I'm not saying I like the look of that, but it does have a distinct
advantage in introducing new keywords.
