biro

biro (pronounced as B-row and mispelling of bro) is an esoteric programming language.

Principle of biro: Don't complicate things

Rules

• Typed language
• Initialization of variables is mandatory
• All global variable declaration or function declaration starts with biro

  biro a : num = 0 // global variable
  
  biro myfunc(a,b) : (num,num,str)

• Local variables are prefixed with smallbiro

  smallbiro i : num = 0 // local variable

Features

• Every loop is infinite loop. Break it using condition.
• No else, only if. Why do we need else when we have if?
• Arithmetic operators
• Logical operators
• No bitwise operators (why do we need them, we can implement them using arithmetic operators)
• Built-in Data types and structures
  • number (always a float)
  • string
  • boolean
  • array
  • stack
  • queue
• Biro have three comparison operator equals or ==, more or > and less or <. Why do we need >=, <= when they can be written as a == b or a > b and a == b or a < b respectively.
