Publisher review:Using Ruby hashes as keyword arguments - Similar to many Rails helpers/methods, a lot of the methods I write often use an optional hash of options, or sometimes just a hash only, to simulate keyword arguments (often using symbols). However, as you have more and more keyword options, setting defaults in this way gets rather tedious. Fortunately, Ruby's Hash#merge comes to our rescue (almost) - it allows you to merge the contents of one hash with another.
The only problem - any duplicate keys in the hash you are merging will overwrite your original hash values - when it comes to setting default values, we want this to work the other way around; we only want values in the defaults hash to be merged if they do not exist in the original hash. Again, Ruby comes to our rescue - Hash#merge takes a block as an argument and will pass any duplicate values that crop up into the block - we can use this block to decide which value to keep.
