Hi, guys!

We can use the range operator in sequence expressions without seq function when it include only a range expression.

1
2

let xs = {1..20} // val xs : seq<int> = seq [1; 2; 3; 4; ...]

This code is evaluable, but undocumented the spec.

expr :=

:

:

expr { comp-or-range-expr } -- computation expression

:

:

comp-or-range-expr :=

comp-expr

short-comp-expr

range-expr

range-expr :=

expr .. expr -- range sequence

expr .. expr .. expr -- range sequence with skip

6.4.11 Sequence Expressions

An expression of one of the following forms

seq { comp-expr }

seq { short-comp-expr }

Is it documentation mistake or bug?
