Agreed. This just comes off as the typical HN post, "I rewrote X program, using Y language, check it out!".
OP is learning Y language, wanted to make a project as a goal. Which is all well and good. But thinking its worthy to be shared seems like narcissism, especially when the description for the repository is, "Half-assed CSS preprocessor." And with 12 commits from the last 5 months, 3 of those being actual code, this isn't a serious project.
This is showing off homework. Though I suppose everyone seeks validation.
