Looks like an easter egg in the lexer to me:
http://golang.org/src/cmd/gc/lex.c
the relevant section is the symbol table:
"notwithstanding", LIGNORE, Txxx, OXXX,
"thetruthofthematter", LIGNORE, Txxx, OXXX,
"despiteallobjections", LIGNORE, Txxx, OXXX,
"whereas", LIGNORE, Txxx, OXXX,
"insofaras", LIGNORE, Txxx, OXXX,
I guess they could be used to test handling of the lexical type LIGNORE, but there doesn't seem to be any "real" ignored tokens.

ugh, their lexer function has a label called 'l0' (el-zero) for the beginning statement. compilers should just be designed to delete your code if you actually use l0 as an identifier in your code.
