Pitch: Implicit Returns from Single-Expression Functions

[masters3d]

Okay +1 but use lambda expression syntax. =>

@Joe_Groff

We had already taken in as a keyword, we couldn't use -> like Java does because it's already used to denote the return type, and we were concerned that using => like C# would be too visually confusing. in made xs.map { x in f(x) } look vaguely like for x in xs { f(x) } , and people hated it less than the alternatives.

I don’t really buy the original argument that -> and => are visually too close. Tell that to commas and periods? if we can happily distinguish between colons semicolons periods and commas we should be able to distinguish between - and =.
