String interpolation at a later stage

[Raj Singh]

x = 'hello'
y = '#{x} world'

desired result = 'hello world'


Please note that variable y has the string interpolation code under
single quotes.

I have these two values x and y. And with that I need to get to the
desired result. Any suggestion on how to do that.

I tried eval y but that won't work because world is not a variable.

try:
z = '"' + y + '"'
zz = eval z

This might not be exactly what you were asking for but might be
helpful none the less:

x = 'hello'
lazy = lambda {"#{x} world"}

result = lazy.call
result = lazy[]

# or maybe even..

def lazy.to_s
call
end

puts lazy # hello world

x = 'goodbye'

puts lazy # goodbye world
