Otherwise for the following code:
```
node test (i: real) returns (o: real);
let
o = 0.0;
tel
```
was experiencing:
```
Fatal error: exception Stdlib.Parsing.Parse_error
Raised at Stdlib__Parsing.yyparse.loop in file "parsing.ml", line 139, characters 8-25

```
Note that `%token REAL` doesn't help to solve this error, but it doesn't seem to be any reason for not having it.
