I use lockfiles (as also most of the developers I know) much more frequently (almost every day) than POSIX locks (almost never, many thanks to GCD and other high-level concurrency features in other languages for that). I'm afraid the argument about overloading doesn't convince me at all, as many terms are overloaded, but that never was a problem as an established context and conventions matter more.</div><br class=""><blockquote type="cite" class=""><div class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><span class="Apple-tab-span" style="font-family: SFUIText-Regular; white-space: pre;"> </span><span style="font-family: SFUIText-Regular;" class="">* If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?</span><br style="font-family: SFUIText-Regular;" class=""></div></div></blockquote><div><br class=""></div><div>Yes, I use yarn, CocoaPods and Carthage on daily basis, and locking dependencies by default was never a problem with those.
