String length limit in F # - error or function?

Question

This code gives you an error in the VS 2010 error list:

let (a: float), (b: float), (c: int), (d: float), (e: float), (f: float), (g: float), (h: float), (i: float), (j: float), (k: float), (l: float), (abcdefghijklmnopqrstabcdefghijklmnopqrstabc: float ) = 0., 0., 0, 0., 0., 0., [], 0., 0., 0., 0., 0., 0., 0.

Adding one character to the last variable as

let (a: float), (b: float), (c: int), (d: float), (e: float), (f: float), (g: float), (h: float), (i: float), (j: float), (k: float), (l: float), (abcdefghijklmnopqrstabcdefghijklmnopqrstabcd: float ) = 0., 0., 0, 0., 0., 0., [], 0., 0., 0., 0., 0., 0., 0.

does not result in an error in the error list.

I have seen this behavior in many ways, but always in long lines. Is it a F # function or is it a mistake?

Answer 1

I am using VS2010 shell with November CTP (not quite sure if this new CTP was created for .NET 2.0 or .NET 4.0)

I tested this code in various scenarios, and there is something strange here. But, of course, there are no "functions" here, since, as @Mauricio noted, both of these let-bindings are incorrect.

Both give a (almost) correct error for the output:

    float * float * int * float * float * float * float * float * float * float * float * float * float,     float * float * int * float * float * float * float * float * float * float * float * float * float * 'a 13 14
