# Given a selector array which is a list of strings with Sass::Script::Nodes
# interspersed within them, return an array of strings representing those
# selectors with the Sass::Script::Nodes removed (i.e., ignoring
# interpolation). For example:
#
# .selector-one, .selector-#{$var}-two
#
# becomes:
#
# .selector-one, .selector--two
#
# This is useful for lints that wish to ignore interpolation, since
# interpolation can't be resolved at this step.
