Fishbone Trehalose is a library addressing restrictions and inconvenient. Examples include:

• Player riding.
• Inconsistent manipulation to CustomData between Entity and ItemStack.
• Lacks of remove(String), remove(Identifier) for Maps in composing objects but only remove(Object).
• Lacks of getOrAdd, getOrCreate, getOrEmpty.
• Lacks of deepCopy for mutable self composing objects which can be composed very deep (eg. 512).
