Suppose I recently found a job posting that works heavily with Technology X, among several other technologies. I have worked with most of the other technologies that they require in a candidate (so I think I really do have a realistic chance at this job, not considering Technology X). While I don't have experience with Technology X, I'd very much like to get some. In a cover letter, I was thinking of writing something like this:
...and I very much look forward to getting the chance to learn Technology X...
After a moment, I was suddenly unsure that this was a good idea. Is explicitly mentioning my lack of experience with Technology X a bad idea, even when framed in the context of enthusiasm to learn? Is there a better way to say this, or should the lack of certain skills (from the job posting) never be mentioned, so as not to draw attention to this lack of skill?
