Could I get a review on the following regex:

All the details:
Years ago a colleague shared a useful little regex for finding wildcard imports in Java, such as the following:

But not:

I'm learning F#. I wrote a function to minimise a function with a single minimum and no maximums. At the bottom I test it on Math.Cos.
What do you think? I've wrote it pretty much as I would in an imperative language. Could it be done more functionally?

I was thinking about how to minimize the code needed to implement a builder.
There is some code that any builder needs to have.
This is:

Is there anyway to make this smaller/more elegant?
