I took a look at Swift when it first came out, and was turned off by the inability to do multi-line mathematical expressions. With the world moving to Swift, I have started looking at Swift 5, and find it still doesn't seem to offer a solution.
In effect, instead of writing an expression like:
a = (b+(c+d)*e + f*g)
I'd prefer to do something like:
a = (b
+ (c+d)*e
+f*g)
and even better still (easy in C):
a = (b // some comment
+ (c+d)*e // some other comment
+f*g) // yet another comment
This sort of thing can be important in comprehensible scientific computation. Is there a way to do it in Swift?
