Added support for Irish. There is some translation trickery so I am double checking several of my choices and will update soon.
Had to use a fair amount of underscores but attempted to find one-word options when possible.
Some considerations:
Irish is Verb Subject Object. There are two words for "is". I went with the copula (is) because of the expected use case. There are multiple words/phrases for "for".
For "continue" I chose the word for "skip" thinking it might be clearer that it is passing over that iteration and going to the next one.
Also tricky for:
"má"        :       "if" (figured not dá)
"seachas_sin"       :       "else" (wanted to say otherwise/in any other case)
and wanted to copy the "elif" combined thing. Suggested "sinnó"   :       "elif"

for -> ag_gach ? (figured "le" or "do" wouldn't be flexible enough)

in -> i, sa, san? (I need to pick one and "i" might mess up some syntax. We might be able to change the grammar so they can use any of the three for "in")

return -> give? tabhair

Thought about "agus" for "while" but then obviously "and" wouldn't work so. Might need to edit this choice later.

Picked aon for "any", and Faic for "None" as it was one word as opposed to "ar bith" or confusing it with "Aon".

Checking all of this with Ellen Corbett.
