shell does something similar with
<<-xxx;
<<[-] word
The shell input is read up to a line that is the
same as word, or to an end-of-file. No parameter
substitution, command substitution or filename gen
eration is performed on word. The resulting docu
ment, called a here-document, becomes the standard
input. If any character of word is quoted with
single or double quotes or a \, no interpretation
is placed upon the characters of the document.
Otherwise, parameter and command substitution
occurs, \ followed by a newline is removed, and \
must be used to quote the characters \, $, `, and
the first character of word. If <<- is used, then
all leading tabs are stripped from word and from
the document.
