Overview

Checks for colons and commas in %i, e.g. ‘%i(:foo, :bar)`

It is more likely that the additional characters are unintended (for example, mistranslating an array of literals to percent string notation) rather than meant to be part of the resulting symbols.

Examples:


# bad
%i(:foo, :bar)

# good
%i(foo bar)
