Lua is quirkier than I realized

• 1-based indexing
• iterate over string is kinda tricky ....
• luarocks doesn't add itself to path
• no builtin formatter for table
• no built-in debugger ??
• repl doesn't have history
• no socket support in stdlib (no stdlib?)
• blocking io by default (for a project like socket)
• no continue in loops - gotta use goto or function call (function call good)
  • actually continue is just a kind of goto ... function calls better
• lua repl local variables are not accessible after the command ends
  • actually sorta lisp like

Oh one more think

→ body, metadata = lcmark.convert('hello *world*', 'html')
"<p>hello <em>world</em></p>
"
→ body
"<p>hello <em>world</em></p>
"
→ metadata
{  -- table: 0x7fb8f761f340
}
