Additional guard methods (match, regex)

[titpetric]

I'd like to implement additional guards, which could be used for matching against the value as a string literal. For example:

.background(@value) when (ismatch(@value, "\.svg$")) {
    background-size: 64px;
}
.background(@value) when (ismatch(@value, "@2x")) {
    background-size: floor(image-width(@value) / 2);
}

Seems the function is quite easy to add to Less, I found the code for other guards right away. What are your thoughts, does something like this have a chance to be included in the master branch? Any comments regarding implementation details?

Implement this as a plugin. While it's not a big deal to feed the language with thousands of functions (yeah, they are cheap to implement) it's not always a good idea to make this just because it's possible.
It's all about use-cases, if there's enough interest it is always possible to move functions from a plugin to the core (after all it already has string replace function, so having corresponding find would not sound too artificial).
