If I read the grammar correctly, then you can do things such as (read "~~~>" as
"desugars to"):
myfunc {|| } {|| } (arg3) (arg4) ~~~> myfunc({|| }, {|| }, arg3, arg4)
The above is a function call with 4 arguments. My wish would be different: I
would want to put lambdas after a function or method call and treat those
lambdas as additional arguments:
myfunc(arg1, arg2) {|| } {|| } ~~~> myfunc(arg1, arg2, {|| }, {|| })
myfunc {|| } {|| } ~~~> myfunc({|| }, {|| })
Rationale: I would always make lambdas trailing arguments, similar to
if (cond) {} {}
And I would rather achieve this effect without currying. Following a block with
a non-block doesn’t seem like a good idea.
Has the other approach been considered?
