== Calling a lua function with \cldcontext and get the return ==
One can execute a Lua code from within TeX and get back the result in TeX by using {{code|\cldcontext}}. Thus, if {{code|myfunction}} is a function of a variable {{code|x}} defined in Lua, {{code|\cldcontext{myfunction(5)}}} returns the value {{code|myfunction(5)}} in TeX. This is equivalent to {{code|\ctxlua{context(myfunction(5))}}}.
== A larger Lua block: \startluacode...\stopluacode ==
