Comments - Manhunter07/MFL GitHub Wiki
MFL supports one type of comment that goes from the beginning to either the ending or the end of the expression. This comment is introduced and ended by a backslash and can be used anywhere in your code. Comments are completely ignored by the compiler and are only there for your own recognition. They can span the whole expression or only parts of it.
Examples
\This is an expression-wide comment
In that case, we may close it at the end of the expression, which will not make any difference:
\This is also an expression-wide comment\
Similarly, comments work after, before or between code:
Sin(4.5) \Let us calculate something\
\And again...\ Length(Obj)
