* Additionally, instead of doing concat("</form>".html_safe), you can do
safe_concat("</form>"), which will skip both the flag set, and the flag
check.
* For the first pass, I converted virtually all #html_safe!s to #html_safe,
and the tests pass. A further optimization would be to try to use
#safe_concat as much as possible, reducing the performance impact if
we know up front that a String is safe.

# Delegates to I18n#translate but also performs two additional functions. First, it'll catch MissingTranslationData exceptions

# and turn them into inline spans that contains the missing key, such that you can see in a view what is missing where.
|
|
#
|
|
# Second, it'll scope the key by the current partial if the key starts with a period. So if you call translate(".foo") from the
|
|
# people/index.html.erb template, you'll actually be calling I18n.translate("people.index.foo"). This makes it less repetitive
|
|
# to translate many keys within the same partials and gives you a simple framework for scoping them consistently. If you don't
|
|
# prepend the key with a period, nothing is converted.
