Option list causes crash

[KenG98]

The following element caused a program crash for me:

link (style no-link-underline):
  content: $$ param character-name
  $$ if param character-name == param page-name:
    option: italic, bold
    color: maroon
  href: $$ param link

Caused

Generation error.

Changing option: italic, bold to option: [italic, bold] fixed it, meaning I've forgotten to parse that comma separated list in compilation and tried to iterate through the values in the list. Changing option to options also results in a problem, it looks like it gets completely ignored.

I'm not sure if this is just in a conditional "if" statement or if it happens elsewhere as well, haven't tested it yet.
