Doesn't "variable" <em>mean</em> "able to change"? Fortunately, this is one way in which BQN isn't crazy. You can <em>modify</em> a variable's value with the arrow <code><span class='Gets'>↩</span></code> provided it's already been defined. This never does anything to the original value: that value stays the same; it's just (probably) not the value of the modified variable any more.</p> -<a class="replLink" title="Open in the REPL" target="_blank" href="https://mlochbaum.github.io/BQN/try.html#code=dGhyZWUg4ouIIHRlbiAtIHRocmVlIOKGkCAzCnRocmVlIOKGkCA0CnRocmVlIOKGqSA0Cgp0aHJlZSA9IDMgICAjIFdhaXQgd2h5IGRpZCBJIGRvIHRoYXQKCjMgPSB0aHJlZSDihqkgMwoKZm91ciDihqkgMyAgICAjIGZvdXIgaXNuJ3QgZGVmaW5lZCB5ZXQ=">↗️</a><pre> <span class='Value'>three</span> <span class='Gets'>↩</span> <span class='Number'>4</span> +<a class="replLink" title="Open in the REPL" target="_blank" href="https://mlochbaum.github.io/BQN/try.html#code=cGnigL9l4oC/dGVuIOKGkCDin6ggz4AsIOKLhjEsIDEwIOKfqQp0aHJlZSDii4ggdGVuIC0gdGhyZWUg4oaQIDMKdGhyZWUg4oaQIDQKdGhyZWUg4oapIDQKCnRocmVlID0gMyAgICMgV2FpdCB3aHkgZGlkIEkgZG8gdGhhdAoKMyA9IHRocmVlIOKGqSAzCgpmb3VyIOKGqSAzICAgICMgZm91ciBpc24ndCBkZWZpbmVkIHlldA==">↗️</a><pre> <span class='Value'>three</span> <span class='Gets'>↩</span> <span class='Number'>4</span> <span class='Value'>three</span> <span class='Function'>=</span> <span class='Number'>3</span> <span class='Comment'># Wait why did I do that </span>0 @@ -46,7 +46,7 @@ </pre> <p>Does BQN not know about capital letters?
