Seq.head<'T> Function (F#)
Returns the first element of the sequence.
Namespace/Module Path: Microsoft.FSharp.Collections.Seq
Assembly: FSharp.Core (in FSharp.Core.dll)
The first element of the source sequence is evaluated at each call. To avoid this reevaluation, you can create a cached version of a sequence by calling Seq.cache.
This function is named Head in compiled assemblies. If you are accessing the function from a language other than F#, or through reflection, use this name.
