'with' proposal

[Elias Athanasopoulos]

Hello!

Wouldn't something like this be cool?

class Foo
def read
...
end
def dump
...
end
def is_empty?
...
end
end

f = Foo.new

with f do
read
dump
draw unless is_empty?
end

Regards,

 

[Elias Athanasopoulos]

irb(main):007:0> class Foo; def talk; puts "hi"; end; end
=> nil
irb(main):008:0> f = Foo.new
=> #<Foo:0x400b32a8>
irb(main):009:0> f.instance_eval do talk end
hi

Uber nice! Thanx.

Regards,

 

[Dan Doel]

Further:

class Foo
def talk
puts "Hi."
end
end

def with(obj, &blk)
obj.instance_eval &blk
end

f = Foo.new

with f do
talk
end
