Lexer error for "a=1.0"

[miko]

For a valid lua code: a=1.0 I get lexer error: warning: metalua failed to compile code that compiles with loadstring. error in metalua? lua-inspect/metalualib/gg.lua:56: lua-inspect/metalualib/lexer.lua:129: assertion failed! 6

I made a workaround, but not sure what is the real fix: metalualib/lexer.lua:129 if tag=='Number' and not content then content=0 end
