Macros beginning with @

If a macrosequence begins with the @ character, then the rest of the sequence is treated as name of the file containing Lua script.

Environment variables in the file name are automatically expanded.
The global (within the environment of the script) variable _filename contains the file name.
Such scripts are easier for debugging and modifications, as they are automatically reloaded at each macro invocation.

Example 1:

    lua: @%FARHOME%\test\test.lua 123, "hello"

Example 2: running script from within the editor.
