Re: Lightweight syntax: a dissident view

[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index] [Thread Index] 

Why everything so complicated?
How about simply this
lambda(x) x == 2
no end, no return, no statements before return, if you want statements
use function() syntax. The lambda goes until end of statement, if you
want to write more in the line use a ';' to separate it like other
statements. A lambda function is also by itself terminated by a ','.
If you need something like 'if', use something like 'select' when in
function-coding-style-mode.
return lambda() x, y ==is==> return function() return x end, y
if you want to return multiple value, use brackets:
return lambda()(x, y) ==is==> return function() return x, y end
I think its a good compromise, not gibberish, still shorter. One can
argue if its worth the new keyword. Might not be, less worth than a
'continue' keyword anyway :-)
