We all learned the symbol in math class. Even non-programmers know what it means. Assigning it any other meaning would be confusing because it’s meaning is so widely known. Every time I bring this up, I am told to just roll my own (which I have)… but it means that my code will now clash with everyone else’s identical implementation (because there is only one sane way to implement it). The fact that there are multiple identical implementations interfering with each other (and no real way to make a significantly different implementation) tells me it really should be part of swift itself. Every time I bring it up, people complain about it being extended ASCII instead of pure ASCII, and that it is hard to type on a German keyboard (those people can either just type ‘<=‘ or use a better editor which autocompletes ‘<=‘ to ‘≤’).</div></div></blockquote><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class=""><br class=""></div><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px;" class="">Nothing is preventing you creating a library which defines the ≤ operator and then including that in your projects for when you want to use it.
