I'm a bit new at Sass, so I'm not sure exactly what all this is called, but I believe this is a discrepancy between normal Sass and pyScss:
Input:
$spacing-unit: 30px;
.footer { width: -webkit-calc(100% - (#{$spacing-unit} / 2)); }CSS output from
.footer {
width: -webkit-calc(100% - (30px / 2));
}Error produced by scss:
In [6]: c.compile_string("""
...: $spacing-unit: 30px;
...: .footer { width: -webkit-calc(100% - (#{$spacing-unit} / 2)); }
...: """)
ERROR: An unexpected error occurred while tokenizing input

calc was recognized as a CSS function taking an expression, but -webkit-calc and -moz-calc weren't. Fixed in 1.3.5. (If you're even still using the prefixed versions by now, ha.)
