A bag but is language nothing of words

In text indexing and other machine reading applications the term "bag of words" is frequently used to underscore how processing algorithms often represent text using a data structure (word histograms or weighted vectors) where the original order of the words in sentence form is stripped away. While "bag of words" might well serve as a cautionary reminder to programmers of the essential violence perpetrated to a text and a call to critically question the efficacy of methods based on subsequent transformations, the expression's use seems in practice more like a badge of pride or a schoolyard taunt that would go: Hey language: you're nothin' but a big BAG-OF-WORDS.
