Programatic Christmas Hymns

Have I been doing too much programming lately? (Or maybe I'm just a nerd at heart...?)

I ask because I strongly suspect I was the only person in the congregation today at Church who had the following Tcl-snippet immediately spring to mind when the choir began to sing a particular hymn:

interp alias {} christmas-messagify {} string map -nocase {l {}}

Can you guess the hymn? (Hint: It's a traditional English carol; ca. 16th-century per this source.)

Wow, I haven't had a snippet of code come up to my head during a hymn. You must be doing programming AND be a nerd at heart, both of which can be great things!

I haven't done Tcl in too long to guess what the hymn is?

A hint; here is the same (or similar) concept using standard Unix command line utilities:

sed -e 's/[Ll]//g'
grep -iv l
awk '!/[Ll]/'
