class Hash
  # Returns a nested intersection of two Hashes.

  # This draws a parallel to &/intersect on Array and Set.

  # FIXME: However, those methods are not recursive, so it may make more sense

Postgres does not really fully support unicode the way some users might expect. Unicode (much to some people's chagrin) supports multiple ways of encoding complex characters.

For instance, the character ば could be:

• ば (\u306f\u3099)
• ば (\u3070)

Like-wise, á and á are different (\u0061\u0301 and \u00e1).

/*
 * Prevent INSERTs or UPDATEs that introduce NULLs. Useful for when the

 * Use like:
 *
 *    CREATE TRIGGER <name>
 *      AFTER INSERT OR UPDATE 
 *      ON <table>

# Chromedriver has this annoying bug where when trying to click a button or

# click the button or link.

# This is a workaround to always scroll the element into view after finding it.
