Hi
How do I correctly write:
puts a,b=3,4 # in 1 line (output should be like puts a,b)
Opti
The big question is: why? What's wrong with using two lines?
For the record, each of `
a
`, `
b=3
`, and `
4
` are valid statements in Ruby, so there'd be no way to tell the parser (or
a human reading your code) that you're doing a single multi-assignment
rather than listing of three statements as parameters. It took me quite a
while to understand what you were even asking here.
Cheers

Hi
nothing, but now I understand, that it could have another meaning (as 3 statements)
bad, that puts((a,b)=3,4) isn't working!

puts(*(a,b=3,4))
But PLEASE just use 2 (or even 3) lines.

Yeah, it's silly.

Exceeding the limits of the interpreter 
puts [1,2] works...

IMO: No,
it comes from the habit of leaving out parenthesis and wrong expectations:
puts(a,b=3,4)
does NOT leave room for uncertainty, you would anyone expect a,b=3,4 to be regarded as a single item?
