Hi there,
I found a strange difference somewhere between Ruby 1.8.4 (2005-12-24)
and Ruby 1.8.4 (2006-02-24).
Here the code:
h = {}
a = []
h[‘test’] ||= a.join ‘c’
ArgumentError: wrong number of arguments (2 for 1)
from (irb):5:in `[]’
from (irb):5
To fix it, I add parenthesis like that:
h[‘test’] ||= a.join(‘c’)
But I found it strange enough to ask the question.
Regards,
