Hello,

I would like to sugget parsing a Number in the value of a query parameter used to set options of a loader.

 if (specialValues.hasOwnProperty(value)) {
     value = specialValues[value];
- }
+ } else if (/^\d$/.test(value) {
+     value = Number(value)
+ }

Is there a reason to parse a Boolean but not a Number? Performances?

Eg. css-loader?importLoaders=true works but not css-loader?importLoaders=1.

Note that having css-loader?importLoaders=true not throwing an error is also confusing, since the css-loader doc states that only a Number is expected. Please feel free to ask me to create a new issue in the related repository.
