Feature summary:
*If the Scribunto module 'strict' (introduced in T209310) is used then no error message should be given if the (global) underscore "_" variable is used. The variable consisting of only an underscore "_" is commonly used as a placeholder when you want to ignore the variable. See of instance the Lua Style Guide at http://lua-users.org/wiki/LuaStyleGuide.

Use case(s):

• A line like for _,v in ipairs(t) do print(v) end should be possible and should not cause an error message.

Benefits:

• All wikis.
