Grammar
exit_statement = "the" whitespace "answer" whitespace "is" whitespace ( integer | identifier ) .
assign_statement = identifier whitespace "should be" whitespace expression .
expression = ( integer | identifier | string | decimal_float ) .
string = "<<" /* any character */ ">>" .
identifier = (unicode_symobls | unicode_letter) { unicode_symobls | unicode_letter | unicode_digit } .
imaginary = ( decimal_float | integer ) "i" .
decimal_float = integer "." digits [ "e" integer ] .
integer = [ "-" ] digits .
digits = digit { ["_"] digit } .
digit = 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 .
whitespace = whitespace_character { whitespace_character } .
whitespace_character = /* Unicode 13.0.0 Character Class: White_Space */ .
unicode_symobls = /* Unicode 13.0.0 Character Classes: Sm, Sc, Sk, So */ .
unicode_digit = /* Unicode 13.0.0 Characer Class: Nd */ | "_" .

Exiting
To exit the program just use the keyword: the answer is <int64>
.
If no explicit exit code was given, 42
is used.
Datatypes
Strings
Strings have to begin with <<
and end with >>
. The use of >>
in the string is not possible.

struct
This may be a valid struct in uff

CAT Mode
The CAT
mode is enabled by default.
The program behaves like a cat. It has multiple lifes.
How many lifes your program has, depends on the target architecture.
Required keywords
These should be valid keywords, but I don't have an idea, what to use them for:
xd
uff
yeet
